Need Windows Mobile Phone Recommendation

I am ready to replace my several year old Verizon XV6700… The 2nd replacement battery is not keeping me through the day any more, it is way too heavy and my colleagues pick on my for using such old technology ;-)

I have a pretty good deal with Verizon, so I’d like to say with them if possible… The killer apps for me today are calendaring and basic email… but I’d love to use the phone as an MP3 player and GPS seems very sexy… I also really like to be able to use my phone as a modem for my laptop…

Do you have a mobile phone you love? What do you think I should get\avoid? Should I try to tough it out until after the holidays?
