hi

I have Nokia E65 at the moment and i would like to buy a htc phone. Should i change my phone and if yes which one is the best htc phone according to you?

if i had a pda phone with windows mobile 5

1. can it stream videos from a home network through a wifi access point?
2. What kind of applications can be installed on it?
3. Is it possible to upgrade to windows mobile 6?
4. what formats of video can i watch on it?

thanks

P.S Sorry if my questions are too stupid because i have never used a pda phone before.
