I also came to Android from BB. I bought the dinc the first day it went up for sale on VZWs site. This device is amazing. Froyo absolutly did not ruin this phone. Cant beat Froyos JIT.
The only thing that I can see that has ruined this device (if there is anything) is the bloat that Verizon puts on it. The last update flashed a useless Verizon app store IMO and put mor apps on it that can not be uninstalled with out Root.
Flashing custom ROMs can take care of this, and with the amount of ROMs out there for the Incredible, bloatware is long gone.
As many stated above, in my opinion, there is not one device currently being sold at Verizon that would make me give up my Incredible. Not one.
MAKE THE SWITCH!
