Acer Aspire S7-391

This Windows 8 machine features a 13.3-inch touchscreen covered in Gorilla Glass 2, a pair of 128GB SSDs in RAID 0, and a Core i7-3517U processor. The S7 achieved a score of 72 on our brand-new WorldBench 8 benchmark suite (which is expressly designed for Windows 8). Read our full review here.

Lenovo IdeaPad Yoga 13
The aptly named Yoga 13 is the most flexible machine we've seen. It bends, swivels, and downward-dogs to perform dual duty as both a Windows 8 tablet and Ultrabook.
The keyboard, trackpad and bezel-less 13-inch multitouch screen are all top-notch and comfortable to use, making Microsoft's new OS easy to navigate by touch, keyboard, or mouse. Lenovo managed to squeeze an Intel Core i5-3317U CPU, 4GB of RAM, and a 128GB SSD into the Yoga, which achieved an overall mark of 60 on our new WorldBench 8 benchmark suite. Whether you need a laptop or a tabletor maybe just something to prop up and watch a movie onthe economically priced Yoga 13 won't disappoint you. Read our full review here.
