Fatal flaw(s): Lack of popular native BlackBerry apps like e-mail, address book, and BBM

The BlackBerry PlayBook, as we said in our review, is a well-designed piece of hardware with an operating system that plucks the good features from a number of sources to make a hodgepodge of an OS that brings some inventiveness to an arena of copycats. That said, it wasn't enough. Most BlackBerry users stick with their BB because of its strong e-mail capabilities and BlackBerry Messenger—neither of which are available on the PlayBook. Yep, not even e-mail. RIM says a future update will bring both features to the tablet, but dropping the PlayBook without those key features in a field of serious contenders was a fail.
