My company is buying me ANY phone I want--as long as it works in the U.S.

I am looking for a great workhorse PDA phone. I liked the Sprint Touch Pro, but it has way too many issues for me, as of now.

I looked at the Omnia, and it was promising, especially with the feedback on the on-screen keyboard. The problem with it, was the touchscreen had issues around the edges, like where the A key is on the screen, in portrait mode, and it kept pushing the S instead. I tried 3 phones, and recalibrated them as well. It's just the design--same as the Diamond and Pro.

Does anyone have a recommendation for me? This is what I am looking for:

1. Full Exchange support w/ certificates.
2. Great touchscreen.
3. Great autofocus camera that doesn't require babying or a tripod.
4. Fast. I felt like I spent more time waiting on Pro than actually using it.
5. The ability to load custom/3rd-party programs.
6. Unlocked GPS
7. Windows Mobile would be nice, but not a necessity. I have grown quite fond of it, and know so many tricks, and love the customization.

Any thoughts? What phone would you guys pick? Is there one coming out in the next few months that you would really want?

The Xperia X1 has really caught my eye...
