DH has had an iPhone since Day 1, and just bought the new 3GS. My boss (tech illiterate) has had several models of Blackberry - and of course I have to program all of them since I'm the tech girl in our dept. I just don't get Blackberries - I can't figure a single thing out without opening the manual! I find almost nothing about it intuitive.
There was an article this week (now I can't find it!) about how Blackberry has a lot of amazing innovations coming soon to their brand, but I don't know.
I guess I'm just an Apple person - and I don't even have a smart phone. LOL I'm looking at getting a smartphone later this year and it's iPhone all the way!
Definitely play with them in the store and see what's right for you!
