honestly..my friendsbhave all converted [except for the nonsmartphone people I know] to blackberry because they see how much abuse mine can take. I got my first one 5 years ago and only considered getting the 3d evo last year but otherwise, I will forever be a blackberry guy.
I'm only 20 but since most of my friends started getting blackberries, my usage has gone up plentyl though its onoy about 3 people. also, I feel like it's less creepy than asking for phone numbers, so I like that aspect. :]
