Over the years I've used the 8700, 8800 and currently the 8330. I've considered the Bold and I'm looking forward to the Storm 2; however, I did buy my wife an iPhone when they were first released.
Overall - I understand that the bb will be more of a hard core business device - but I can't help being drawn to the iPhone's sex appeal - the simple design - the simplicity in use - and that beautiful screen.
I wish the Storm - at the very least - had the same size (or larger) screen! That might make me stay with BB.
Also - with the new mobileMe service - the iPhone will have a pseudo BIS/BES functionality.
Hmmmm - I'll wait for the Storm 2 - but I find my self growing weaker . . .
