There are two reasons I'm wanting a Win8 tablet over the others.
- ability to easily mount network shares and access from any app. Android can do this if you root and get a custom kernel. PITA. IOS doesn't seem able to.
- maybe play some x86 turn-based strategy games or RPGs.
More CPU power will definitely be welcome for PDF/CBR/CBZ.
you should look at the kickstarter games , there will be alot of great stuff for windows tablets coming from that.
