That's a good point. Ok, so maybe MS would be the one to bite. If only to beat out a potential competitor to windows phone and to pick up that slice of the market.
Consider me convinced, that might just work out well for them, if they're going to switch anyway it might as well be to a company that is already well represented in the enterprise. How they're going to give those users the blackberry experience is beyond me though, but that would probably not stop an acquisition.
