It's not about what you as an individual wants, it's about what the target market wants. If the manufacturer thinks a $500 1 inch thick tablet that has a 6 hr battery running at Max TDP is not marketable they won't make it.
The mass market will get arm powered tablets. The x86 tablets will be for a diffrent class of user.
wco81 If not $200 7 inch tablets, looks like there will be 9 or 10 inch tablets around $300.
I bet the surface rt costs less to make than the fire 8.9 hd or whatever its called.
