Touch screen stopped working when I used it for taking notes since it got too hot to respond to touch. These shouldn't be used to take notes on apparently, or anything else that requires use of touch screen more than just a little. Lenovo makes good alternatives for this, but I won't go into that. When I tried to return it, the seller used scare tactics to try to have me keep it, such as a 20% restocking fee and such. Not cool. If the product doesn't work right, I shouldn't be charged anything extra to return it. I told them it doesn't work right when taking notes for school, and so they "tested it" and it didn't display those symptoms... As if they have any incentive in the world to prove me right. It's a sort of shady business honestly.
