I can't think of one reason why I would install this. Oh wait, how about I've been using Windows since Windows 3.0 and I know how long it takes them to get rid of bugs? Some could be really serious ones, too. Installing a preview version of something from Microsoft can be nothing but a bug festivity. This is meant for people who'd like to help Microsoft debug it. I only use Windows for professional audio work, so I need a completely stable OS for that. Still using XP and W7 for that. For everything else - Linux. There's no chance I'll change to something else any time soon.
