Just upgraded from a 700P. I love the Centro's size....

Now that I have had it a few weeks:
1. I miss the flsahing light when the phone is on.
2. I miss the reset button
3. So far I have not been able to find a "great" case
4. Battery life is as expected, no worse in light use, a little worse in heavy use


All comparisons to P700
Overall, very satisfied...

If those are the only things you miss, I can understand why you are so happy. My list is longer than that (coming from i500) but after a while you have to "upgrade" whether or not you want to.
