There are several DROIDs at work undergoing testing, and we just got two Nexus Ones in today. The DROID suffers from having a keyboard that is simply too flat. It's large, yes, but the uncertainty with regards to typing is too high for any reasonable speed. The Nexus One is probably good but, well, no keyboard.

Aside from being the best Android device with a keyboard, I'm not sure what's so great about the DROID, honestly.
