Acer has upped the Ultrabook ante today with the Aspire S5, which the company claims is the world's thinnest. It's also the first to include a Thunderbolt port.
The S5 (pictured above) weighs in at a lean 2.65 pounds and is a mere 0.44 inches at its thinnest point (0.59 at its thickest). (In comparison, the new MacBook Air is 0.68 inches at its thinnest point.) It comes with a 13.3-inch LED-backlit screen, Intel Core i7-3517U Ivy Bridge processor, 4GB of RAM, and 256GB solid state drive. In addition to the Thunderbolt port for high-speed data transfers, it also includes HDMI and USB 3.0 ports in a hidden "MagicFlip" I/O section.
Of course, you'll pay for the sleekness and (relative) power of the S5. It will cost $1,399.99 when it goes on sale during the last week of the month.
If you're looking to spend a little less but still want a new Ultrabook, Acer has also updated the Aspire S3 with options like Ivy Bridge processors and a champagne color choice. The base model, however, still comes with a Sandy Bridge Intel Core i3-2377M processor, though that helps Acer sell it for just $648. Even with optional 256GB SSD and Ivy Bridge CPU, the highest priced S3 maxes out at $999.99. The new S3 models will be available starting next week.
