Sony Vaio Pro 11 - Lighter-than-Air ultrabook

 

 CNET - 

The good: The Sony Vaio Pro 11 weighs less than 2 pounds and uses a fourth-gen Intel Core i5 to deliver long battery life and very good everyday performance. It has an excellent 11.6-inch 1080p touch screen and is competitively priced for its features.

The bad: The Pro 11, like its competition, has a nonremovable battery (though you can add an external battery), few ports and connections, and integrated graphics only. System memory is maxed out at 4GB.

The bottom line: The superthin, superlight Sony Vaio Pro 11 is everything we expect from an excellent ultrabook.

Lenovo Thinkpad X1 Carbon: The Ultralight, Semi-Rugged Carbon Fiber Ultrabook

Gizmodo -

Tablets may be the next big thing in mobile computing, but don't count out ultrabooks just yet. At least not until you've given Lenovo's Thinkpad X1 Carbon—a feather-weight, carbon fiber workhorse a closer look. It's tough, it's light, and you don't have to be an office drone to crave it.

The X1 Carbon it the latest addition to Lenovo's popular X1 series. Despite a spacious 14-inch screen, the X1 Carbon tips the scales at a scant three pounds—making it the lightest rig of its size—thanks to its carbon fiber roll cage. The screen displays at a native 1600x900 resolution. The system supports up to 8GB of integrated DDR3, runs 64-bit windows 7 Pro, and has that Intel Ivy Bridge goodness you've been hearing so much about.
