Read Jobs' comments about going nuclear on Android and you can see this is just an execution of a strategy he set in place. If there are no more suits by Apple against Android vendors in the next year I will buy you a case of beer.
Even in the talk where he introduces the iPhone, Jobs says something along the lines of "we have over 200 patents for technologies that went into this device . . . and we aim to protect them!" and then everyone applauds. Kind of eerie looking back on it.
