Hi, I'm thinking of purchasing a Windows 7 Samsung Slate. I am trying to find out if there is a hardware difference between the old one and the new one. Internet searching has not turned up a clear answer. There seems to be little price difference between the older and new ones (by new ones I mean the ones set to come out Nov. 7 2012). Also I would like to know if they have fixed the issue with screens coming off at the corners.
