The Acer Aspire S7 Ultrabook line has been named an International CES Innovations 2013 Design and Engineering Awards Honoree by a preeminent panel of independent industrial designers, engineers and media. As thin as .47 inches and weighing as little as 2.29 pounds, they are as thin as a tablet, include Windows 8, and 13.3-inch or 11.6-inch full high-definition touch screens. The lid on the S7-391 tilts back 180 degrees, allowing it to be used flat against a table or desk.
