I got this touch pro yesterday in Orlando while on vacation. It is simply as nice an upgrade as the mogul was to the apache. So far things are more responsive and I used PIM backup to get all my contacts and various settings from my mogul. I think touchFLO is cool, but nothing major if you have been using the diamond skin on the mogul.
In order of most impressive upgrades from the mogul:
1.) LCD and Screen resolution.
Color quality and 4x the pixel resolution makes this easily the most standout feature.
2.) Opera Mobile:
I am able to see and read an entire dynamic updating fantasy football page. Skyfire was way better than internet explorer for this, and Opera kills skyfire now. I have not installed flash yet in opera mobile, so i may still need skyfire.
3.) YouTube Application:
I was able to get youtube running just fine on the mogul, but it is now faster, the interface is more friendly,and the resolution looks great. Bringing up an episode of the little rascals for my 5yr old was flawless on first run.
