Some argue that this deal will drive a wedge between Google and makers of Android/Linux smart phones. Nothing could be further from the truth. This gives everyone in the Android/Linux gang a big brother who carries a big patent-stick.
While Motorola competes with other makers of Android/Linux stuff, Motorola and the others are all part of the Open Handset Alliance and share code and standards. Buying Motorola puts Google into the same position as the other partners as far as having to implement the software in actual gadgets. There could even be an explicit cross-licensing amongst the members of the Alliance. We shall see.
