Well I had the Touch Pro for a little over a week now and here's what I've noticed (in no particular order) that is better than the Vogue.
1) TP is much more responsive than the Vogue
2) The touchflo 3D is actually usable, I never used the Cube on the touch
3) Yes, it's heaver, but it does feel nice in the hand.
4) Pictures are noticeably better.
5) Volume was a bit low, but the audiopara files I found made a noticeable difference
6) Signal quality seems better
7) The TP offers a much better browser experience, with the built-in opera
The music player is usable, but its no ipod.
9) GPS seems to be much quicker and more accurate (could just be me)
10) I haven't had to soft reset the phone once since I've own it. My Vogue needed bi-weekly resets to cope with life...
11) Tethering
seems faster
Things that could be better
1) Battery life.....
2) The phone does get a bit warm during heavy use
3) Regular headphone jack, this can't be so hard for them to do.
Overall, I'm very happy I made the switch to the Touch Pro.
