  • Dell Vostro 3450 Battery

    The XPS 12 shares a hardware feature with the Microsoft Surface tablet that really improves the Windows 8 user experience: a recessed Windows home button below the screen. Press it and the display swaps between the traditional desktop and the Modern tile-based UI no matter which way the screen is facing.Other handy features include a volume rocker and screen orientation lock on the left side of the body where they can be accessed when using the XPS in tablet mode.On the subject of volume the stereo speakers fitted on either side of the body are excellent. The XPS is the best sounding laptop I’ve come across since the B&O-equipped Asus N73.The backlit keyboard and trackpad feel very much as they do on Dell’s other XPS-series Ultrabooks: the chiclet keys have a positive action and the keyboard deck is rock solid. I find the key characters excessively stylised, but that’s the only criticism I can make.While the Inspiron Duo’s screen locked into the frame using magnets alone, the XPS adds four physical catches. This makes for a slightly cheap-sounding ‘click’ when the screen latches in place but has the benefit of holding the screen more firmly in the frame and making it less likely to spin free when tapped near the top in laptop mode.

    Two small rubber nubs sit on the front corners of the keyboard deck to soften the impact of the deck and the lid/screen. And because the lid closes in the same way no matter which way round the screen if facing, once folded it stays folded, just like a normal notebook.The screen itself a lovely looking, though glossy, 1920 x 1080 affair - a decent resolution for such a relatively small notebook screen. Crisp as a new ten pound note, with excellent colour representation and plenty of brightness: 400 nits, since you ask. It is also superbly reactive to the touch, ranking along with with the Apple iPad 4 and Google Nexus 10 tablets in the pantheon of quality touchscreens currently on the market.With a Core i7 chip, 8GB of 1333MHz RAM - not standard; the baseline is 4GB - and a 256GB solid-state drive - which is standard - the XPS 12 I have here goes like stink. The only downside to the spec is the integrated Intel HD 4000 graphics, but you don’t buy an Ultrabook if you want a gaming machine. To put some numbers to that statement the PCMark 7 test suite returned a more-than-decent score of 4965, largely thanks to the SSD

    Another useful side effect of the SSD and Windows 8 combination is a prompt start up time: 14 seconds dead from cold to fully up and running.On the other hand, this being an Ultrabook, wired connectivity is pretty poor: two USB 3.0 ports, one mini DisplayPort, 3.5mm audio and that’s your lot. No Ethernet, no SD slot and, of course, no optical drive. I blame Apple for the spread of this sort of idiocy but at least the Intel-made 2.4GHz and 5GHz two-antenna 802.11n Wi-Fi card is up to snuff.I didn’t have much luck on the DIY front. Despite removing all ten torx screws, I couldn't get the back off so I can't tell you how easy it is to swap out the SSD or the battery. Yes, the battery is built in; another thing to blame Apple for - and Dell for following it.Trying to boot Ubuntu off a USB stick proved equally fruitless. In short, this is not a machine for the home tinkerer or the more casual Linux buff.The 47Wh battery ponied up 4 hours 45 when looping a HD video with the screen at 80 per cent brightness, while the unreasonably brutal Powermark 1.2 test drained it in three hours and five minutes. In everyday use, I got between five and and six-and-a-half hours, which is a decent score for such a skinny laptop.

    When Dell released the Inspiron Duo, no one else of any note was offering anything similar. Not so now, as a number of Intel's Ultrabook have tried to tap into the public's demand for tablets to sell more laptops. The XPS 12 is case in point, but it's not the only one. Toshiba has the Satellite U925t, Sony the Vaio Duo 11 Hybrid and Lenovo the IdeaPad Yoga, to name but three.The Duo 11 and the Satellite are the closest to the XPS 12: both have clever, but intricate, fussy mechanisms to allow the screen to slide face up over the keyboard. I don't think these will stand up as well to regular usage, not to mention the knocks and bumps all working laptops take, as the XPS 12's simple swivel-in-the-frame system.But even that isn't as robust as the double-jointed hinges Lenovo has put on the Yoga. You literally fold the screen back and round. Easy. A downside is that the keyboard isn't covered, but it is disabled in tablet mode, and the keys are recessed so they don't press against whatever the tablet is laid upon. The only problem: the 11in Yoga is a Windows 8 RT device, so it's limited by the range of apps you can run on it. The bigger Yoga has a third-generation Core i for a full Windows 8 experience, but 13.3in is getting a bit large, in my view, for a tablet.

    Dell has really hit on something with this spinning screen convertible notebook malarkey. Rotate the XPS 12’s display one one way and you have an no-compromise Ultrabook - though as an Ultrabook, it is a compromised notebook: no optical drive or Ethernet, for starters. Flip the screen in the other direction and you have an excellent if slightly heavy Windows 8 tablet. Granted, it’s not cheap, but I defy anyone to buy one and not think it money well spent. CES 2013 Nvidia’s Project Shield seems positively daft at first thought. Who in their right mind would launch a new handheld gaming device today? If Sony and Nintendo can’t win over the millions of folk who play games on phones and tablets with their dedicated gaming handhelds - and very strong gaming brands - how the heck can a manufacturer of graphics chips?However, Shield has a neat trick up its sleeve that suggests Nvidia may not have lost the plot entirely.It’s easy to look at the clamshell Shield - it looks like a tiny laptop comprised of a screen clipped onto an Xbox controller - and draw immediate and not very flattering comparisons with the PlayStation Vita and the Nintendo 3DS. It’s big, angular and, compared to a smartphone or 7-inch tablet, a bit clunky.

    Nvidia CEO Jen-Hsun Huang, while showing off the gadget at a pre-CES 2013 announcement event, admitted that the design isn’t final and could yet change, but as it stands Shield looks like the kind of handheld someone might have come up with 10 or 15 years ago.That said, the specs aren’t retro. There’s a quad-core Tegra 4 chip incorporating a “custom 72-core GeForce GPU” and quad-core ARM Cortex-A15 CPU; enough battery power for “five to ten hours” of gameplay; Wi-Fi; Android Jelly Bean; MicroSD storage; a 5-inch 294ppi 1280 x 720 display; a “bass reflex, tuned port audio system with twice the low-frequency output of high-end laptops”; and HDMI output.Still, it’s hard to imagine gamers playing with it on their way into work on the Tube, even if they can play “any game on Google Play” and others that Nvidia will make available on its TegraZone site.But it’s in the home where Shield may win friends and influence people. There’s the HDMI output, which, we assume, means you can play games on your TV, thus combining console and controller into one, though only wireless HDMI will give the player true freedom from a long cable stretching out to his or her telly.

    More importantly, Shield will be able to access a networked PC’s Steam library, taking control of the computer to running titles on the big box while it acts as a remote display and controller over an “ultra-low latency” wireless link. That’s handy, perhaps, if you want a quick play session and you don’t want to sit in front of your monitor.But there’s the problem: any gamer keen enough to want Steam compatibility - of sorts - is surely going to be far happier firing up their computer and playing in front of a decent sized screen, whether it’s a monitor or a connected TV with Steam in Big Picture mode?Valve has its own hardware in the pipeline, and then there’s the Ouya Android console too, though neither will be able to let you play games on the move, at least so far as we know today.Huang said Shield could go on sale in as short a time as a few months hence, but the device demonstrated is still just a prototype. Of course Nvidia isn’t saying anything about how much the thing will cost - or how many it expects to sell.

  • Dell Latitude D610 Battery

    For the less well-heeled gamer, Iiyama’s ProLite E2473HDS-B1 is a lower-cost LED-backlit display with a decent set of inputs and a fast response time, without any fancy controller add-ons or support for 3D. It uses a TN panel which can’t match the sheer image quality of IPS, but it certainly outpaces it with a gamer-friendly response time of just 2ms. It’s also one of the best-performing TN panels around, making it a good all-round display for when you might want to knuckle down and do some actual work. If you’re a gamer at heart, but want a decent display for all your other tasks, the E2473HDS-B1 is a great buy.Featuring a 23in IPS panel in a stylish, slimline enclosure, the aptly-named Blade 2 has been made as thin as possible by moving as much of the technical gubbins as possible into the base – which features a row of wipe-clean touch-sensitive buttons as well as VGA and a pair of HDMI inputs. There’s no self-assembly required with this monitor as the hinged base folds flat for storage. Although contrast and black levels weren’t quite as strong or consistent as I’ve seen from other IPS panels, picture quality clearly outclasses TN displays and an overdrive feature helps tweak response times for gamers.

    The 21.5in Philips S-Line 221S3UCB is very different from the other displays I’ve looked at here. It’s not particularly stylish, nor does it offer particularly exciting performance. It comes with no controls whatsoever – not even brightness, and has no video inputs. This is because this monitor uses a single USB 2.0 input for both power and display connections, making it a very simple addition to your Windows laptop with the minimum of fuss. Yes, there are now 23 and 24in USB monitors available, but these tend to require more power to run making them more demanding on your laptop.Sometimes you simply don’t have the room for both a monitor and a TV. Samsung’s T24B750 handles both functions in a single futuristic-looking device with its off-centre stand holding the 24inch TN-based panel aloft like a flag. Screen quality isn’t as good as an IPS display, but this is much more than a standard monitor with a Freeview Tuner slapped on the back, the 24in T24B750 supports Samsung’s Web-connected app-driven Smart TV functions, a built-in wireless access point and wireless Full HD video from your laptop using WiDi. You can also watch video from your android phone with an MHL connection.

    ViewSonic’s VX2370Smh-LED is a striking 23in IPS monitor. Its frameless design lends it a distinctive minimalist appearance where the monitor itself seems to all but vanish, leaving the picture hovering as if somehow suspended in mid-air. It has an unexpected and very profound effect on concentrating the mind on the picture and is also great for multi-monitor setups. The display produced impressively accurate colour right out of the box, although a little backlight bleed was present in the lower left corner which was only really visible in a darkened room. It’s built in stereo speakers and multiple inputs make it a great all-round display at an excellent price. Infosec daredevil John McAfee claims he became a spymaster in Belize after giving laptops infected with espionage malware to police and government officials.McAfee, who moved to the central American low-tax haven some years ago, further claimed he supervised a ring of 23 women and six men as operatives, and tasked them with striking up relationships with targets and extracting secrets.

    The eccentric millionaire hatched the scheme after a crack Belizean cop squad raided one of his properties, shot one his dogs and seized hundreds of thousands of dollars in kit. The Gang Suppression Unit was searching for a supposed meth lab and guns but found nothing. No charges were brought but the incident put the founder of antivirus biz McAfee Inc at loggerheads with the authorities.In a quest to exact revenge after receiving no apology for the bungled bust, McAfee set himself up as a spymaster, as explained in a lengthy article on his official blog:I purchased 75 cheap laptop computers and, with trusted help, installed invisible keystroke logging software on all of them – the kind that calls home (to me) and disgorges the text files. It also, on command, turns on and off the microphone and camera – and sends these files on command. I had the computers re-packaged as if new. I began giving these away as presents to select people – government employees, police officers, cabinet minister’s assistants, girlfriends of powerful men, boyfriends of powerful women.

    I hired four trusted people full time to monitor the text files and provide myself with the subsequent passwords for everyone’s email, Facebook, private message boards and other passworded accounts. The keystroke monitoring continued after password collection, in order to document text input that would later be deleted. So nothing was missed…I next collected my human resources for the complex social engineering I would have to do. I arranged with 23 women and six men to be my operatives. Eight of the women were so accomplished that they ended up living with me. It was amazingly more efficient and they were easily convinced to check up on each other. One was so accomplished that she became a double agent and nearly got me killed.The tech tycoon claimed he infiltrated two national telcos using his operatives in order to tap the phone lines of his enemies. He further claimed various social engineering tricks were put into play.In all, McAfee reckons he set up an extensive spook network with tentacles into every aspect of life in Belize. By his own account, the malware maverick was looking for evidence of corruption to turn the tables on those who trashed his property.

    But what he apparently found were details of extramarital affairs and far more disturbing information. He alleged data uncovered showed that officials were helping Hezbollah-aligned terrorists to get Belizean passports and identification cards.Mostly this supposed intelligence came from electronic taps on immigration department computers but McAfee claims he had some human intelligence as well:I had located an individual working in immigration who was trustworthy and willing to talk. I discovered that an average of eleven Lebanese males were given new identities each month. One month there were sixteen. McAfee claims he sent one of his female operatives to befriend one of these Lebanese militants, who supposedly turned out to be sexually violent and intent on using Belizean papers to gain entry to the United States:Belize is clearly the central player in a larger network whose goal is to infiltrate the US with individuals having links to terrorist organizations. What is different today from the wholesale Belizean passport selling of ten years ago, is that the false citizenships that are created for these men are coupled with a network of handlers designed to move the individuals, and their cargo, into the US Making a laptop with a screen that spins within its bezel isn’t a new idea. Early in 2011, Dell tried the trick with its Inspiron Duo netbook, but sadly that proved to be a woefully poor device. Now Dell is trying again, this with Ultrabook hardware and Windows 8 as the basic ingredients.

    It helps that, unlike the Duo, the new XPS 12 isn’t built down to a price. The entry level Core i5 version will set you back a cool £999 but the full-fat Core i7 version I have been testing will take £1299 out of your wallet. For that sort of cash I expect something rather special.The money certainly gets you some quality materials. The body is made from a mix of carbon fibre and aluminium, while the screen is faced with Corning Gorilla Glass. The whole thing is very solid, with only the aluminium screen frame demonstrating a wee bit of flex, though not enough to keep you awake at night.The notion is that when you want to use the XPS 12 as a laptop, you rotate its 12.5in screen so its facing you across the keyboard and trackpad. But it you’re in a tablet mood, you spin the screen round to face the other way and close the laptop’s lid.While the black and brushed aluminium colour scheme is undoubtedly smart and business-like, all the black surfaces are matte which means greasy fingerprints quickly multiply.At 1.45kg the XPS is 200g heavier than a 13in MacBook Air. That’s not enough to get bent out of shape over in my book and while I wouldn’t want to hold the XPS one handed for long, the Dell machine is certainly light enough for prolonged two-handed use in tablet form.

  • Batterie HP COMPAQ 6730s

    Enfin, le dernier smartphone est connu sous le nom de code Mercury ». Il disposerait d’un écran de 4,5 pouces avec un rapport d’aspect 3:2, sous lequel on trouverait un clavier QWERTY. Un processeur Qualcomm Snapdragon 625, 3 Go de RAM, 32 Go de stockage interne et une batterie d’une capacité de 3 400 mAh seraient logés sous la coque du smartphone. Deux caméras seraient disponibles, un capteur de 18 mégapixels à l’arrière et un autre de 8 mégapixels en façade. Il arriverait au 1er trimestre 2017.Si les rumeurs exactes, il semble que BlackBerry envisage d’étoffer sa gamme de smartphones. Cela commencerait par le lancement d’une alternative plus abordable que le haut de gamme BlackBerry Priv, puis un modèle avec des spécifications plus puissantes.Reste à connaître les prix de ces nouveaux modèles. Avec un Priv assez cher, peut-être que BlackBerry souhaite commercialiser des smartphones plus abordables.Lorsque Google a introduit Now on Tap il y a un an, la fonctionnalité semblait être un must-have pour tous les appareils Android. L’idée d’appuyer sur un bouton, et obtenir davantage d’informations sur à peu près tout ce qu’il y a sur votre écran s’avérait fort excitante !

    Mais une fois que la fonctionnalité a été déployée, de nombreuses personnes ont trouvé que l’outil n’avait pas une grande utilité. Je ne suis pas la seule personne qui n’a pas réussi à être rassasié par les réponses renvoyées par l’outil. Mais, Google a ajouté de nouvelles fonctionnalités à Now on Tap qui pourraient le rendre beaucoup plus utile. Par exemple, la dernière mise à jour apporte le support de la traduction de texte sur une page, entre autres choses.Si vous utilisez le navigateur Web de Google, Chrome, pour surfer sur le Web à partir d’un appareil Android, ce dernier peut déjà traduire automatiquement le texte qui s’affiche. Mais si vous utilisez un autre navigateur ou une tout autre application qui peut parfois afficher le texte dans une langue que vous ne pouvez pas lire, vous pouvez maintenant appuyer longuement sur le bouton d’accueil de votre appareil, et choisir la carte Traduire cet écran ». La traduction est initialement disponible en anglais, français, italien, allemand, espagnol, portugais et russe.

    Une autre caractéristique est la possibilité d’utiliser l’appareil photo de votre smartphone depuis une application pour identifier les sites (monuments, etc.) célèbres ou d’autres éléments. Enfin, vous pouvez utiliser l’appareil photo pour scanner des codes barres ou des QR codes (ces graphiques carrés que vous avez probablement repérés sur les côtés des bâtiments, des panneaux d’affichage, et des arrêts de bus) en utilisant Now on Tap. Il suffit de scanner le code pour faire une recherche Google pour ce produit, puisque l’outil peut maintenant extraire tout le contenu numérique (lien vers le site, ou la photo) qui se cache derrière ces boîtes noires et blanches opaques, monolithiques.Enfin, Now on Tap se dote d’une nouvelle section Découvrir », qui est destinée à aider à en apprendre davantage sur les choses qui vous intéressent ». Par exemple, si vous lisez un article sur NASA, vous verrez des vidéos pertinentes sur YouTube, des photos et des articles de presse.
