This is just my personal opinion... DO NOT
do it, hang on to your Incredibles for as long as you can (or keep it as a back up phone)... I truly believe that most will be hard pressed to find a device that is as good, let a long better than our Incredibles.
In fact I am seriously contemplating reactivating my DInc until VZW and HTC works out whatever the Thunderbolt's problem is (random reboots and loss of connectivity) not mention I really miss my trackpad lol.
I have not been this fustrated with a phone since my Droid Eris, so it is always nice to have an amazing fall back phone... heck I am probably going to reactivate my DINC when I get home from work... But this just my personal opinion
