One of the big goals of the ultrabooks was to offer highly portable computers. Many early examples offered very thin and light systems but the trend for more affordable offerings meant many grew in size. Touchscreens are also a big since the release of Windows 8 which is built around the interface. They do tend to add to the cost of a system. Acer has decided to pair up a touchscreen with their latest 11-inch ultrabook that weight an impressively little 2.2 pounds at just a half-inch thick. Is this the ultrabook to get for those looking at a small and lightweight system or does it sacrifice too much for portability? Find out in my review of the Acer Aspire S7-191-6859 ultrabook.
