Samsung Ativ Q vs Lenovo ThinkPad Helix vs HP Envy x2:Best performer is.........................

  Samsung Ativ Q                                                                                                                                Samsung ATIV Q hybrid laptop will also come with the capability of being able to transform from a laptop to a tablet instantly, by smooth sliding. The design of the Samsung Ativ Q is impressive: with a 13.3-inch screen, it certainly feels more laptop than tablet, but the superbly high resolution display (QHD 3200x1800, which equates to a 275ppi) means that you'll be more than impressed whether you're checking out Windows 8 (the full-fat version, not the confusing Windows RT some users will have encountered) or Android 4.2.2. The Samsung ATIV Q is a powerful hybrid device. With an Intel Core i5 processor at its heart, the Q also features backing from Intel 4400 HD Graphics and 4GB of RAM. Windows 8 makes a good foundation for the Samsung ATIV Q, with Android present to provide some much needed glamour. Sadly, Samsung’s TouchWiz UI is missing, leaving plain old Android to hold the fort. Keeping things running smoothly across the two platforms, Android apps can be pinned to the Windows 8 homescreen, creating seamless shortcuts between the two content levels. the Ativ Q comes with Samsung's S Pen stylus with 1024 levels of sensitivity and SideSync software which means you can use a smartphone or tablet as a second screen or have it mirrored on the larger display. The Ativ Q really comes into its own because of its dual-OS setup – Windows 8 and Android 4.2 Jelly Bean come pre-loaded. You can switch quickly and easily between the two with appropriate buttons and even share files such as the photo gallery. The ATIV Q is made mostly from magnesium, is admirably thin at 13.9 mm, and seems pretty solidly built. Its screen slides and tilts up to reveal the keyboard, but it then can also be flipped over to face the other way, kind of like a cross between the convertible designs of the Sony Duo 13 and Acer Aspire R7. Samsung ATIV Q also comes with an impressive specs sheet. The Samsung ATIV Q has a 13.3-inch display with a mind-blowing resolution of 3200 by 1800 pixels. That results in a pixel density of 275 ppi, which is really impressive for a tablet of this size. According to Samsung, the display shines brightly enough to be usable outdoors. A Haswell-based Intel Core i5 processor delivers all the processing power, paired with 4GB of DDR3 RAM and Intel HD Graphics 4400, all the while consuming a reasonable amount of energy. Samsung claims that the tablet should be capable of getting up to 9 hours of battery life. Storage-wise, there's up to a 256 GB solid-state drive tucked in there, although the actual amount of space available to the user should be less. Last but not least, there's a 720p front-facing camera outfitted for video chats. The Samsung ATIV Book Q is a hybrid with a completely new design, QuadHD+ (3200×1800) and weighing 1.2KG. Based on Haswell it should offer a lot of performance and great battery life. It comes with a dual operating system. Windows 8 and Android are provided with seamless switching making this a unique proposition.                                  Price:$1500
VS                                                                                                                                                           Lenovo ThinkPad Helix                                                                                                                             The ThinkPad Helix is powered by a third generation Intel Ivy Bridge processor, up to Core i7 and up to 8GB of DDR3 1600MHz RAM. Aiding performance is an SSD of up to 256GB so its performance is top-notch. You’ll be able to choose between Windows 8 and Windows 8 Pro.The Lenovo ThinkPad Helix will be available in an array of spec configurations, but the one we saw  demonstrated was a mid-range example, with a Core i5 processor. Core i7 options will also be available. The ThinkPad Helix uses current Ivy Bridge-generation CULV Intel chips, backed-up by 8GB of RAM and a 256GB SSD. The screen and base are each under 2.0 pounds, but that's on the hefty side for an 11.6-inch system. That said, it's 20mm thin, qualifying for ultrabook status, and can run processors up to Intel's current-gen Core i7.Travel-friendly features include 3G/4G antenna options, NFC chip, and a spill-resistant keyboard.The Lenovo ThinkPad Helix feels like a hybrid roadwarrior. It's reasonably light, especially in its class, offers great build quality and careful attention to detail in its construction. It may not be a beauty, but it's one of the better full Windows 8 hybrid designs out there.                                                                                                             Performance and battery life
A 1.8 GHz processor and 4GB of RAM may seem small on paper, but in practice the ThinkPad Helix is a surprisingly capable machine. Both the Windows 8 tiled interface and desktop ran smoothly on our review unit.
Browsing in either Chrome or Internet Explorer, we could get a dozen tabs going before performance started to chug. This is with the tablet docked in its helpful stand, which provides extra cooling and allows the processor to overclock a little.
The performance enhancement is noticeable, and the fans generate minimal noise. This is by no means a gaming machine, but we were able to play some Half Life 2: Episode 2 with an acceptable framerate.
The stand also provides additional battery life. With its help, we generally got 7 to 8 hours of web surfing and word processing. As just a tablet, the Helix got between 5 and 6 hours. That's not bad at all, certainly better than a Surface Pro, but one can't help but think of what Haswell could've done for this machine.
Price;$1,499                                                                                                                                               VS                                                                                                                                                               HP Envy x2                                                                                                                                                The Envy x2 impressed us. Its outstanding industrial design really shows the potential of a tablet/laptop hybrid. The HP Envy x2 has a clean, comfortable design and feels lightweight in tablet form. It has excellent battery life, and works just as well as a laptop as it does as a tablet.                                                             Performance:                                                                                                                                               Unfortunately, as soon as we start talking performance we’re confronted by the fact that Clover Trail is still Atom, and Atom is still not in any way, shape or form a performance chip – and that 2GB RAM maximum doesn’t help here either.Don’t get us wrong, for navigating through Windows and average daily use such as browsing the web and running apps or light programs, the Z2760 in the HP Envy x2 runs smooth as butter. Performance is consistently superior to that in the netbooks of yore, especially when it comes to HD video playback and light multi-tasking, and most non 3D-gaming apps you’ll find in the Windows store should run without a hitch.
However, proper multi-tasking; running intensive HD video simultaneously with another program; or using demanding programs like an image editor can still quite easily bring this kind of machine to its knees. In other words, as a tablet the x2 performs admirably, but as a laptop replacement you have to be prepared to put up with its limitations.
3D gaming in anything but the most casual titles, meanwhile, is also a big no-no. Even at minimum settings our test games simply refused to run or crashed after getting through the menus. Mind you, this is not surprising given that Intel’s integrated GMA 3600 chip paired with the Atom Z2760 is derived from an old PowerVR design the benefits of which Windows drivers don’t fully bring out. Hopefully updated drivers will eek out more performance.                                                                                                                                   Battery life:                                                                                                                                                   Battery life is impressive, living up to HP’s claim of seven hours when we streamed video from BBC iPlayer. And, of course, there’s a second battery in the keyboard, which provides an additional seven hours of battery life. No ultrabook that weighs a similar amount can claim to last this long.                                           But, The laptop mode is top-heavy, and the awkward tablet detachment mechanism isn’t perfect; it has limited ports; and a slower Atom processor means in performance it's far behind most ultrabooks, even though it’s priced like one.                                                                                                                           The bottom line: The HP Envy x2’s capacity to be a full Windows 8 tablet or dock with a keyboard works as well as advertised, provided you’re willing to live with slower performance at a high price. You’re paying for style.
