According to CRN (sorry, couldn't find a URL to correspond to the paper version), 3rd quarter handheld sales declined. Palm actually increased slightly, from 753K units to 824K. Sony was the second place vendor with 350K units, a big jump from last year's 93K. HP was in third, with 290K. The others that made up the top 5 were Toshiba with 104K and Casio with 100K. Toshiba's share represented a jump, while Casio managed to lose almost half its volume. Handspring didn't make the list, and was presumably in the "other" category which totaled a significant 769K.
It will be interesting to see what the coming year brings. Dell's Pocket PC is going to shake up Pocket PC pricing in a major way - [it-director.com...] - and this could have major implications not just for Windows-based portables but for Palm-based systems as well.
