Incredible cons:
Materials. Or a plus one for it being lightweight and a better pocket phone.
Battery life is on the ugly side.
AMOLED screen is showing it needs another gen or two for it to be dead on.
No Keyboard.
Sense UI does mean upgrades will be slower. But if you like out of the box, then don't care about that.
Incredible Pluses:
AMOLED screen, still could be a Plus for you if you don't mind the drawbacks.
Form factor and weight. Again, pocketable.
Sense UI. Handy apps and widgets. Slightly tweaked on screen keyboard.
Droid Cons:
Heavy
Keyboard ain't the best.
No Sense UI.
Slower processor.
Droid Pros:
Best radio out of all the Droid phones. Regardless of carrier.
Great speaker.
Great battery life (for a smartphone)
Screen colors and contrast are downright dead on. If I pull up one of pics online, it's so close to the real deal. Only misses a little shadow detail.
I would have thought the Incredible has a total speed advantage. But after my Droid FINALLY got the 2.1 upgrade, I say the Droid is pretty snappy. And the advantage seems nil.
If you like the Sense UI, get the Incredible. The only REAL Con is the battery life. If you have a dedicated desk at work, just by another micro USB charger.
