1. Sure, but the comparison isn't going to be easy. For instance, comparing year for year figures for WP7 vs. iPhone when each was released is about as fair as you can get, and yet that comparison is (somewhat rightly) always knocked down as comparing apples to oranges. IOW, both sides will spin these numbers and fanbois on both sides will claim victory while no one else will care.

2. Not sure why that matters, but sure. I expect the numbers to be staggering, and probably over inflated when you consider most laptops/ultrabooks are going to include touch interfaces from this point on.

3. Really can't agree here. The point of W8 is supposed to be "no compromise". You know, the "combination of a fridge and a toaster". Microsoft doesn't want a decline in desktop usage.

4. Oh, so customer satisfaction is more important than revenue? Funny... there's a whole industries (such as cell phone and cable service) where customer satisfaction is abysmal all the way around, and yet the businesses are highly successful. In any event, there are enough Microsoft haters around that it's unlikely any survey could accurately measure this, even if there were an increase.

5. Sure. That one's a given, as all PCs will include W8 going forward. Even Vista had great numbers here.
