Never been an issue for me with the aGPS devices that I have used. Yes, your right it can take awhile but that is not unusual in any device that uses straight GPS. HAd to wait a few minutes the other day for my Garmin device to properly sync with the sats where I live.

I do not own a Droid X so can't speak for it specifically but I do own a Droid 1 and I have not had any issues catching a GPS lock with no cell phone coverage. You would obviously need a GPS program that can work offline also like Igo. You could always cruise down to the verizon store and load Igo and then go in to plane mode and see what happens.

One other thing to think about. Some devices need the phone radio to be on to power the circuit that powers GPS. I had this with my Samsung Omnia.

Hope this helps.
