I'm puzzled, your comments seem to claim simultaneously that:

* There is not a battery life problem on Windows machines.

* The battery life problem on Windows machines is not surprising.

No, I didn't say #2, I said it's not surprising that the Surface Pro gets poor battery life. My comment about this whole controversy is that you cannot project 1 computer's battery problems to the operating system. My Windows does get poor battery life but we haven't seen any evidence of that. Clearly it can get good battery life as there are real-life computers running Windows that get great battery life.
