>Motorola does their own hardware, they already use Android exclusively, already had a working relationship with Google (Droid, Xoom), and Google doesn't seem intent on totally absorbing Moto like MS did Danger.
That's a really hard tightrope walk for Google. The last one to try this model of both making hardware and licensing the OS was Apple during the nineties and we all know how that ended.
They need to make money from Motorola (currently it's at breakeven) to justify the purchase price for shareholders, but without pissing off the other OEMs like Samsung/HTC. I am not saying it can't be done, but it's very very hard.
