Sounds like we had the same acer tablet :) I used it till an update early last year said the graphics driver was no longer recognized. It's sitting on my shelf in its little leather cover, can't bring myself to throw it out.  I was sad Acer wasn't still making them, the HP build quality isn't as good and it's bigger so not quite as portable but with an onboard optical drive it fulfills my needs for being away from home longer term, while still functioning as my tablet so doesn't just get put away when I am home with my desktop.
