Why not a netbook though, I've had various Psions over the years and the file conversion can be a bit buggy at times and I don't think they're supported any more (leastways the Psion7 etc. aren't). I suppose if you're looking for a smaller form factor the the Psion 5 series would fit the bill but typing large amounts on them can be frustrating, depends how big your hands are. Pretty sure all of the original Psions use a serial cable to connect to computer so you may want to factor that in as well. As I said, I loved and used Psions from the 3 onward but everything else stopped working nicely with them :-(
