i bought this the last time it came up. it came a little scuffed up, but it wasn't bad enough to send back.
i installed windows 8 (after backing the system up...no restore discs, easiest way was to burn an image of the drive to an external hard drive), but had to go searching for the drivers for the touch screen (after the installation)...i was going to send it back when the touch screen didn't work after the change. i ended up downloading and using the windows 7 drivers, and the touch screen works fine now (i tried looking for windows 8 drivers...they didn't work).
i have to say that even the windows 7 experience with touch was nice (i would have been happy to keep windows 7 on it). personally, having tried windows 8 on touch/non-touch devices, i wouldn't want windows 8 without the touch screen.
overall, i'm happy with the machine, and while i still look around at other options, they are all much more expensive and don't offer anything i am lacking with this one or can easily add myself for a decent price (like RAM... i haven't put in more RAM yet, but that is next on my list).
this machine serves my purpose (developing windows 8 apps), and i needed it to run windows 8. for all other activities, i tend to use my trusty windows 7 or windows xp machines.
