The 11.6-inch Acer Aspire S7-191.The Aspire S7-191, which has the 11.6-inch display, is 0.47 inches thick and weighs 2.29 pounds. The Aspire S7-391 has the larger 13.3-inch screen and a Gorilla Glass 2 cover. According to Acer, the screen is built to withstand minor falls. Given Windows 8’s tablet-friendly interface, Acer built the 13.3-inch display to fold all the way back so you can use the ultrabook as a tablet. Both ultrabooks have a special hinge that keeps the screen upright (when in ultrabook mode) so you can touch your finger to the screen without knocking it back.
