Smartphone: if you want an amazing phone with great Outlook intergration.

Pocket PC Phone Edition: if you want a Pocket PC. (with some phone stuff in there too)

I know the Pocket PC is fully /featured/ as a phone, it doesn't have the same feel as having a actual phone. 

The Smartphone is much closer to the size of a normal phone, so it'll actually fit in your pants. Plus you  can do it /all/ with one hand. (mail, games, web, anything!)

I have an MPx200 with Smartphone 2003 and I love it! I think you'll love a Smartphone too! Smiley
