I ordered one two weeks ago. When it arrived it would not let me register the computer online. The screen initiated, then immediately expanded into a full zoom mode and then froze.  I was unable to complete the registration. I called AST and after they could not resolved the problem, I was told to return it to Amazon for a replacement.  I did and a replacement was sent in a timely manner.I got the second pc and started to get it registered.  Nearly everytime (2 out of every three times) I touched the keyboard it would freeze or change the zoom settings making it impossible to type a single sentence without changing the screen setting dramatically.  I called again to customer support and was told to send it back and a refund would be made.  I asked about the warranty I purchased for the product but I have to wait for the email from the manufacturer before can receive the refund for that product.
