This is pure and simple direct response to the Nortel pattent auction. G got burned on that one, loosing out on 6000 patents that will surelly be used agints them.
Well now they have 17 000 new patents and counting to defend Android, which will get attacked on all sides, you can bet on it.
The physical phone business is pretty much worthless, with the amount of serious competition here is.
Good move for G.
