I'm looking to get some sort of palm pilot. I'm just not sure of the model. Wifi sounds like it would be fun, but I'm not sure if it's worth the extra price. For Mac compatibilty, are Palms the way to go, or could I also consider getting a pocket PC? If I go Palm I was wondering what models you would suggest. I mainly need the Palm for addresses, to do things, calendar, etc. But, wifi would be fun. I'm sort of interested in the Palm Tungsten C and the Palm TX (if I got wifi). Does anyone have some feedback about these units? If I don't go with wifi, does anyone have some info on the z22? Thanks.
