Hey guys, with 10 days till the release of Windows 8 I have been getting more and more involved in my tablet to buy search. But I need your help as i'm not much of a tech wizard so I don't know if the Tablet can do what I need it to.   

Firstly it needs Windows 8 with the ability to run all of my windows programs. But my main concern, and this is where i'm in and out, is will the speed of windows 8 tablets be enough to do my normal PC activities which include, watching movies, web, all office applications, programs like Rosetta Stone, and a few games like Age of Empires and NFS.
As for HDD memory I mostly use external HDD's so storage isn't a big thing for me, but connectivity is huge. USB, 3.0 would be nice, HDMI, SD, MiniDisplay Port are the connections I use.
Solid battery life is also needed, 7+ would be nice and then with the keyboard adding an extra kick that would be perfect. So with that a keyboard that connects as well.
11in and up, 12in would be great for screen size but i'm not THAT picky if its not 1080p.
I know I have special requirements but that's what I love about Microsoft/Android, they see what the people need and make a product that meets those needs.
Hopefully my needs aren't too picky.
I know within this will be do I go intel atom processor or i5, again i don't know which would be able to handle my needs and give the best pay-off to battery life. 
Or is all this too much and i'm better off buying a ThinkPad Twist?

Thanks for your advice and time, MUUCH appreciated!
