Any ability of a duel boot between windows 7 then adding windows 8?
If you partition your hard disk, then I would imagine you can install Windows 8 along side 7. I'll be doing this.
This is the first version of Windows I've ever been looking forward to. I loved Vista, and now 7, but only after upgrading. The new metro theme looks beautiful, and I love how it's so HTML5 oriented. HTML applications should also now use IE 10, meaning it should be easy to build very pretty non-metro HTML5 desktop applications; i.e. something like Steam.
It also seems to be a huge overhaul of the whole OS, even down to the new file system, which is hopefully the result of all their WinFS work.
