size...
The YOPY is a good bit smaller and lighter than
the Palm, Pocket PC, and the Sharp. It weighs
in at 5 oz. My only complaints are the lack of
contrast control and some printing issues with
the desktop control center component. YOPY
customer service has been great though and
they expect to fix the contrast and printing
issues shortly. And,yes, the YOPY is very
high quality. I'm going to try porting some
apps to the YOPY via G.Mate's YDK.
