I am both a spotter and a ..."spottee?"...
I have seen quite a few people with BBs when I'm at work...and I always try to talk to them and make sure they know about Crackberry right off the bat...then, if it turns out they are a fellow 8100 Pearl user, I make sure they know about ColorPearl...
But I have also BEEN spotted by BB users, since mine is virtually attached to my right hand...and they have always come up and said ooooo, nice Pearl, or something similar.
The community is GROWING!!!:D
