Do you really believe Apple "wanted" Samsung to license? That offer might just be lawyering. Apple knew that offering a license would eventually help in court. It established a price for a court to work with. It was a price that Apple knew Samsung, with lower margins, either couldn't or wouldn't likely pay. Samsung couldn't counter either because that would be an admission.
Best Buy should mimic Amazon's internet business. It is easy to order online. Repackaging and returning an item online is more time consuming. Knowing that an item can be returned to a physical store would be Best Buy's advantage.
I think Microsoft will price the surface with a very low margin to grab market share. They now want Apple's model of selling the software and the hardware. I don't think they care about their "Partners" anymore. For now, most of their "Partners" have no choice with regard to an Operating System anyway.
