I have to say, they've made a ton of improvements since the last release. I'm still not super happy with it (and it still feels like Vista) but it's definitely taken many steps ahead.

I still don't think anyone is going to be using the metro menu. It's just not what people want from Windows.

Edit: Wait, nevermind, I got it to crash within fifteen minutes. Apparently if you remove a tile from metro while moving it to a new column it will hang the metro menu and break the windows key (at least for me).
