I have the haswell version of this for taking notes in class, and it's a nice device, but there are some quirks about the version I have. It seems to auto thermal throttle at about 60 Celsius as it never turbos higher than that on IBT or prime 95. The screen could be a tad bit nicer quality and brightness, the touchpad and keyboard are not as responsive as my older xps 1645 laptop.
On the bright side it is a nice device for browsing the internet and light gaming like oblivion, minecraft, and Skyrim on low details 720p. The only gripe I have about this is that the touchpad does not register on Skyrim and oblivion and it has disconnect driver issue's with 8.1 too) All in my version 13 inch version:http://www.bestbuy.com/site/split-x2-ultrabook-2-in-1-13-3-touch-screen-laptop-4gb-memory-128gb-solid-state-drive/1902357.p;jsessionid=6F2E150C5B87A9A62AA2DC58AC033EC9.bbolsp-app03-199?id=1219066875875&skuId=1902357&st=split%20x2&cp=1&lp=2
Is a fairly good deal at the 650 I paid for it given the 10 hour surfing and typing life I enjoy with it docked.
