I'm new to pda's and I'm looking for one that can support MPEG-4 video. Like the TH55 and TJ37 clie's for the price and the WIFI. Checked out the UX 40-50, and like those too, but price holding me back and 40 only has bluetooth. If you have a better choice let me know. I am also on a Mac and PC, if that matters to ya.
