Day one, 15 minutes out of the box, the on/off switch did not work. Acer agreed....and said  I could send it back (their cost) and they would repair it and return it to me. I said no...I wanted a new machine. They said....no.Also, this machine had two different SNID numbers on it...very unusual. So it is a defect right out of the manufacturing process and Acer wants to fix it and have me to try it (i.e. experiment with it) again.Bogus !!!!!!
