Electronics freak

What's up I was wondering what cell phones everyone is using. I am looking to get one, and I need some ideas on what to get. The criteria I need to fill are PDA and phone together with anything else thrown in.

So far I am looking at the new P800 from Sony Ericsson. It has everything above and an mp3 player and camera. Its kind of pricey and new so I am not sure about it. If anyone else has anyother suggestions that would help out the best.

Thanks
