I've noticed that the new window animations are quicker and it makes 10 feel way faster than 8.

You should be fine, you would have to work very hard to break anything using virtualbox. It is pretty straightforward too.

Yeah apparently the search is going to have Cortana which will be interesting but not quite interesting enough for me to have it on my task bar. That stuff should be in the start menu or on hotkeys...

I cant wait for someone to figure out how to remove the search and desktop buttons from the taskbar, other than that though I think it is fantastic so far. New window transitions make the whole OS...
