At least the nice feature will be that you can choose what you want to have (Metro, old desktop).

I've been using Win8 for about a month on the developer's preview and I have to say, I really like it. I unfortunately don't have it on a a touch screen tablet (just a HP 8540p laptop) and I can say the Metro interface is pretty rough with using a mouse. They didn't get it right that the screen follows the mouse so you have tou use the scroll bars (don't know if that'll be changed in the beta/later on or not -- hopefully it will).

Nice thing is you can currently just rename the c:windowssystem32shsxs.dll to something else (-old) and you'll have the good ol' desktop for all users that you create. Nice thing too is you can just rename it back and get the metro interface back if you want.
