First of all, the overheating was terrible. You couldn't run anything without overheating. It actually overheated while installing the damn thing turning it on for the first time. Went to >90C (200F) in less than a minute and would shut down if you dared to open two programs at once.
While charging, it was even worse. You basically couldn't do anything with it except some basic browsing (no flash or youtube!) if you didn't want it to burn.
Next the performance was bad. You couldn't watch a movie over 480p really without it lagging after 10 seconds.
I think after less than a year the hard drive crashed (it was a toshiba drive).
Tossed it out and put an SSD in, also installed Ubuntu instead of the Windows 7.
Things got better and it ran smoother, but watching movies was still a no-no and overheating was still an issue.
Apparently it was a construction mistake where both the processor and graphical chip were under the same heat-sink.
