I think it will. Now show me a PC with that spec with the form factor and battery life - i.e. usage pattern - of an iPad. Your ARM tablet wont be able to run legacy software. Your x86 tablet wont have 12 hours of battery life and be thin and cool (in both senses of the word).
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.
