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 Asus Transformer Book TX300 The Asus Transformer Book TX300 is a rare hybrid with a Core i7 CPU, a high-res screen, and smart dual hard drives -- there's an SSD in the tablet half, and a larger hard drive in the keyboard base.The screen is fantastic, as is the overall build quality found across this aluminium-clad laptop. Quality oozes from every panel, and while it's in no way lightweight, the TX300 is thin enough to slip into a bag, although you'll feel it as you walk around.The tablet packs in a 38Whr battery, which gave us pretty good performance in Battery Eater Pro. We managed to get 2 hours and 28 minutes, which roughly translates to about 4-5-hours of real world usage. This is not bad considering we haven’t counted the battery in the dock as well.It runs Windows 8 on an Intel Core processor and also includes four gigabytes of RAM. Long-term storage is provided by 128Gb or 256GB solid state drives. This makes the system both a convertible and an Ultrabook. ASUS claims this is a world first, though that’s not exactly true. Dell and Lenovo have offered convertible Ultrabooks for months.The Asus Transformer Book TX300 is a great example of a hybrid laptop/tablet. Once the screen is attached, it turns into a true laptop with a high-performance processor and an excellent display. And as a tablet it's perfectly honourable.
But, The system is awkwardly top-heavy, and you feel as if you're fighting the touch pad at every turn.
The bottom line: Asus adds a lot of what I've been looking for in a hybrid to the Transformer Book, but no one has yet really nailed the perfect laptop/tablet combo. Specifications

If Sony’s battery claims ring true and its battery pack accessory is priced right, this could become one of the best Ultrabooks in town.The Sony Vaio Pro 13 weighs less than 2.4 pounds and uses a fourth-gen Intel Core i5 or i7 processor to deliver long battery life and very good everyday performance. It has an excellent 13.3-inch 1080p touch screen and is competitively priced for its features.the 13.3-inch Full HD 1,920 x 1,080 display is clearly the true star of the show. It’s immensely vibrant and bright, which makes it great for watching high-definition films and video, and the touchscreen is responsive and adds a new dimension to the Windows 8 interface.Battery life wasn’t quite what we were hoping for either. Sony claims battery life of up to seven hours – which can be increased to 18 hours with an optional battery pack – and we did get a respectable six hours and 20 minutes out of it when streaming video from BBC iPlayer.
But, The Pro 13, like its competition, has a nonremovable battery (though you can add an external battery), few ports and connections, and integrated graphics only. Memory maxes out at 8GB.
The bottom line: For those who want an excellent ultraportable laptop with more than just the latest Intel processors, the Sony Vaio Pro 13 Touch is it. Specifications
