Blackberry or Iphone

Right now I prefer the blackberry for business purposes. I know a lot of Blackberry users that love the keyboard but are a little jealous of the lack of applications. The apps for the iPhone are a huge plus. I probably would get an iPhone if it had a flip-out keyboard. That way it would have both a touchscreen and physical keys. Also, I know a lot of people prefer the e-mail on the Blackberry. It wouldn't take much for Apple to make some improvements to their e-mail. I think that they would win a lot of Blackberry fans if they made those changes.
