i know a hardcore blackberry fan. and she has not been impressed with the changes they made in blackberry os 7. i am not even sure that blackberry would like a UI that is a pretty close copy of android. they are used to blackberry working in a certain manner. and that is very different from how android works. this alone could turn out to be a problem for Blackberry. they are probably going to alienate their hardcore user base while not having enough to attract android fans.
