Google probably did buy Moto for their patents.
But this surely will not hold up Apple one bit. If the patents were being infringed Motorola is trying hard to stick it to Apple in the courts now.
Maybe Google has better Lawyers.
More than anything. Once the Samsungs and HTC's start jumping ship to Microsoft, this will give Google one company that is their very own.
All in all, the biggest losers will be Google. That is one big chunk of change.
