I've been playing with the consumer preview of Windows 8 for a few days now. The desktop bit looks good, but I absolutely hate the Metro bit. Why would I want to run fullscreen applications on a 27" screen for example? Waste of space. Been modifying it to my needs, so removed most of the tiles in Metro and added a shutdown button on the task bar. Also installed Winamp (why would I need a Microsoft account to play music with the built-in music player?). Don't get me wrong, the Metro interface is great for tablets. I might even want to trade my iPad with one of those. I've added some screenshots of my current setup :)
