Well, this is a fun rumor, especially since it jibes with my prediction for 2011 that BlackBerry and Nokia will surrender to Android.
Makes a ton of sense for BlackBerry, but raises the same old fragmentation concerns for Android developers. The PlayBook is said to have a pretty typical standard tablet specs, e.g. 1024 x 600 resolution, but BlackBerry’s phone vary greatly in their display sizes.
Anyway, very interesting stuff.
