I bought this for about $25 more a month or so ago and haven't had any problems with it. Just had to install the latest nvidia drivers on ubuntu or else there was terrible performance. But other than that it's been pretty decent. Only two negatives I've noticed:
Battery life is not great - I get maybe 90-120 minutes on battery just using internet and a text editor.
Built in speakers are kinda quiet, even with all mixers maxed out I can barely hear the thing unless the room is silent.
One or both of these may be specific to running Ubuntu on it or specific to my laptop, but they haven't bothered me too much for how cheap it is, YMMV.
