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 Acer Iconia W700 The Acer Iconia W700 can work as a tablet or a small desktop, and it has a high-res screen and excellent battery life.The tablet's performance was also responsible for a lot of that joy. With an Intel Core i5-3317U at the helm, along with 4GB of DDR3 SDRAM, Intel HD 4000 graphics and a 128GB solid state drive, the Iconia W700 can give laptops a run for their money when it comes to speed. It had no problems streaming video from the Web (from paid services such as NBA.TV, as well as YouTube and Vimeo), and it was responsive when it came to browsing Web pages, loading apps and flicking through photos. It really is perfect for media consumption.Acer claims the Acer Iconia W700 battery (4,850mAh capacity) battery lasts eight hours. This is a little optimistic. We found it was closer to six hours during normal, everyday use. Were it a laptop that would be ok, but it's not great for a tablet and unlike most tablets it has a proper dedicated charger - it doesn't charge via USB.
But, The non-adjustable stand limits viewing angles, and you'll need an external mouse or touch pad for efficient Windows navigation.
The bottom line: One of the only Core i5 slate-style Windows 8 systems we've seen, the Acer Iconia W700 asks few compromises for full-time use, but the design isn't for everyone. Specifications

Optical DriveNone Price;$959.99 VS Microsoft Surface Pro Making your mind up about the Surface Pro is less about what it is and what it does and more about what you want out of a tablet. As a hybrid PC it's an undeniable compromise - but that's no bad thing.The Microsoft Surface Pro fits a full ultrabook experience in a compact 10-inch tablet. Thanks to the ingenious Type and Touch covers, it offers a comfortable interface and typing experience. The clean, crisp design and sharp 1080p screen rise above the competition.
But, The battery life is disappointing, and more ports would be nice. The 64GB model barely has any free storage. It costs as much as a regular laptop, especially because the cool keyboard cover isn't included by default.
The bottom line: The Surface Pro's gutsy design successfully reinvents the Windows 8 laptop by cramming an ultrabook experience into the body of a 10-inch tablet. Those wanting to go all-in on the tablet experience won't regret buying the Surface Pro, but we're holding out for a future, more polished generation of the device.
