Rumors are going around today that Microsoft could actually look to takeover RIM. "RIM is a massive strategic fit" for Microsoft, said Canaccord Adams analyst Peter Misek. "I'm fairly certain they have a standing offer to buy them at $50 (a share)."

Could RIM's stock price fall far enough for Microsoft to move in? It's possible. The bigger question is whether or not Microsoft would improve the BlackBerry or screw it up.
