Instructions: Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.
Input: I bought this item on the basis of existing reviews. I was not let down. I have been using the Infinity since August 2012. There is the occasional crash, but not too often and everything works fine again after a reboot.<br />Apart from the fact that this tablet (with the keyboard dock) looks fantastic, it's also a really robust machine.<br />The ambient light feature is my favorite making it comfortable to see your screen and its contents at any time of day in any light.<br />The battery life is reasonable, it's also handy that the keyboard dock has its own battery too and can be charged separately.<br />Finally, I find the shape of the screen beats the iPad hands down. It's a much better format for watching those all important HD movies.<br />I wouldn't swap my Infinity for any other tablet.
