seems like iMessage is apples attempt to pry away those people keeping their Blackberrys solely for bbm. I loved bbm when i had my bb, but now that I look back on it, it isn't all that great. Hopefully iMessage doesn't disappoint and have some catches with where it works and between what devices all the features work with the best. ie: if the now responding ...... works between UI's (iOS and android or if it only works between iOS5 devices)
