How to use Snap in Windows 7

Join Windows Tuesday Oct. 11th for our Tech Tuesday Live Twitter Chat at the Bellevue Microsoft Store to talk about PCs and IE9.
Umm... time on Tuesday?
I would be interested in hearing about high end tablets/slates (ie running core i5 ASUS EP121 etc) that are on the sales floor or expected soon.
Sub text: I am looking for the current best platform to develop WINRT apps on (I didn't go to BUILD so the Samsung BUILD tablet isn't an option)
Thanks and good luck with the chat.
