I was a blackberry power user for a long long time (going to when they were essentially paging devices). I finally decided to give up the email-optimized blackberry because they were lagging in other areas (apps, wifi, camera, internet, screen size, music, video). I am glad I switched because these other features are so much better that it's worth the slightly worse email experience. I tried the Droid with slide out keyboard but it's really not as good as blackberry's. I then got an iPhone. I have been a long-time Apple anti-fanatic but I have to say, this is a great device. Being able to check awardwallet, ITA and check-in via various airline apps are samples of little advantages over the Blackberry. With that said, if you are single-mindedly focused on email, I would stick to the Blackberry. I think that's like sticking to a bicycle instead of upgrading to a car because you are single-mindedly trying to optimize fuel efficiency, but everybody's got their preferences.
