As a user it's a tradeoff. May be the x86 tablet won't have 12 hours battery life while still being as thin as the iPad but maybe I can trade a few hours of battery life or a few mm of thickness to get my legacy quicken app running on my tablet. What is cool is that as an end user I will have a choice to go either way.

Processors are getting better with each passing day. I don't think we are too far off from seeing x86 on a thin PC still getting a good battery life.
