packing more power into a PDA or portable device seems kinda odd, why not just use the PDA as a teminal too your home desktop machine connected via wireless link (wifi?) then I could run photoshop on my PDA :)
That OQO is a pretty cool little device. Of course, with either of these devices input is a b*$@^! On one the keyboard is sooo small that my fingers would have difficulty and on the other - the same bane as with all PDAs - that darn stylus (fingers). It's the only reason I don't use my Visor more.
