None of these are good reasons for Microsoft to buy the failing RIM. The Playbook is a joke, the distinction between enterprise and consumer is rapidly fading, and while yes, RIM is profitable, they won't be for much longer. And re-energizing RIM employees? By all accounts I've read they're as pissed and frustrated as could be. Not an employee base I'd want to acquire.
My guess is the author of this article owns RIM stock...
