I've seen even the currently-crappy tablets in <i>heavy</i> use in the medical field, I'd bet largely for signatures (I've signed on 5 separate tablet PCs at different locations, over several years).  They're also capable of being carried around and used while walking.<p>That said, they are still crappy, and most require a powered pen (won't anybody learn from Wacom?  Or did they somehow gain a ubiquitous patent, which the patent office isn't supposed to allow?).  At the end of the day, though, they're just Windows with a couple marginally-intelligent tablet-oriented applications (ie, big buttons).  Certainly not optimal.
