Timely thread... I just got my Droid X a few days ago.
I'm still very much a novice, but some of my favorite
apps might prove to be (I have them installed, but haven't used anything very much yet):
* 3banana notes
* Aldiko bookshelf
* Calendar pad
* Citation index (LDS scripture references)
* Gospel Library (LDS scritures)
* Mototorch LED (use camera flash LEDs as flashlight)
* Pandora
* Realcalc (easy to use scientific calculator)
* Speed Test (test internet connection)
* Tricorder (various sensors)
* WeatherBug
