Not nitpicking at all. That picture in the link ludi provided is obviously a fake - or at least miss labelled.
The thing has a (maybe slightly photoshoped) HDMI port. HDMI ports didn't really exist in 2002.
It looks like a mildly photoshoped version of the Netbook Navigator Nav 10T
Windows 7 tablet (look at the second picture, the side and ports are identical). More likely it is a picture of a generic Asian Windows 7 tablet that is similar to the Nav 10T... Either way, fake.This is what an MS tablet looked like in 2002
That aside, I am unable to review the design patent in question. If it is indeed for something as general as "rounded corners on a rectangular mobile device" then I suppose I agree it is interesting that it was awarded. However, I doubt such a patent would have much chance standing up in court. Particularly since other companies have been making rounded corner mobile devices for the past few years...
