Asus Zenbook Prime UX31A Asus essentially maintains performance parity with the similarly priced Acer Aspire S5, but includes a better display.
The Asus Zenbook Prime UX31A is a premium computer with a price tag to match. The build quality is excellent, the performance is great for an Ultrabook and the screen is top-notch.
Sadly, the battery life makes you think twice about its good points when you're spending that amount of money - we're just not sure that it's worth it for all that many people.
If you want a high-end Ultrabook, we recommend the Asus Zenbook Prime UX31A as long as battery life isn't your main concern. Specifications

Optical DriveNone Price;$1,299.00 - $1,671.99VS 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.
Price;$1,499 VS HP Envy Spectre XT 13-2050nr Slim and lightweight, the HP Envy Spectre XT is portable, well-built, and easy to use, with a great keyboard.
But, The design doesn't stand out as much as the original Spectre's did, and its battery life won't get you through an entire day. From a premium product, we'd expect a higher screen resolution.
The bottom line: A high-end laptop at a mainstream price, the HP Envy Spectre XT gets much of the look and feel right, with only a few missteps.
