Just bought a Sony Vaio T13 ultrabook - enjoying it a lot.
Was really skeptical on the whole touch screen laptop concept before I got to play with a bunch of them at work. Now I find myself using it a decent amount (particularly with Win8).
Not a powerful ultrabook by any stretch - i5, 6gb ram, hybrid HD/SSD, no graphics card, no dvd drive. But nice, lightweight, good keyboard, decent enough trackpad (although with external trackball and touch screen I don't really need it). Really good little machine. Going to upgrade to 8gb of ram from my older laptop (1 year old, same ram type). Might do 16gb since laptop ram prices plummeted yet again it seems.
Haven't tried to play any games on it yet, other than the basics of solitaire and mahjong. Mainly just an email/web browsing/smartglass laptop. Soon enough will get my Surface and then not sure what the hell I'll really use it for, but I wanted a new touch laptop after playing with them a lot.
