I was a hardcore corporate BB user, for heavy email and calendar use. I skipped all the iphones, and I was a BB addict. After one month with the iphone I will never go back. Keyboard needs a few days to adjust, but it guesses your words and learns on the fly. I was most concerned about the keyboard, but after a few weeks, it is a total non issue. The apps for iphone are great. It interfaces with my corporate exchange server. It opens the doors to new ways of productivity that BB just cannot do. I would encourage you to take the plunge. I doubted the iphone for years. I was wrong. In my work (heavy BB corporate user), the iphone is great. Really great. Took me a month to really understand how powerful of a device it is for business....
