My wife and I have them. (becuase for some reason she thinks if I get a toy she needs one too HAHA). I got the palm because I am always out in rural areas and small towns. My Katana II wouldn't get signal in a lot of places that the palm does. Plus I can keep an eye on my email and reply with things such as "yeah...of course I'm still at the office"
DO NOT BUY THE BROWN LEATHER CASE FROM SPRINT. The brown leather dye rubs off onto the buttons and wont come off. Sprint is aware of it but they still have them on the shelf. I haven't found a case that I like yet, I tried the clear plastic one and the body glove type (that looks like a use condominium) didn't care for them.

soduko
much easier for email and messaging
calender
-'s
ring tones that come with the phone are numerous but still
havent found a case I like yet
It's been a good phone for me and I haven't had any problems with it like a friend's blackberry phone.
