I think this is a smart move. When BB was on top, letting other devices on to their messaging platform would have been a mistake (which is, incidentally why iMessage is single-platform). Now that they're trailing hard in market share, making BBM cross platform means blackberry users are less isolated. They have had to switch strategies, but that they are actively adapting to their new reality is a good sign. They should have done this a year ago at least.
