I've been a Gentoo user now for a good 7~8 years and every time I've tried playing with Windows again the one thing that I immediately notice and immediately get annoyed about is the lack of 'work spaces' ( http://www.whylinuxisbetter.net/items/virtual_desktops/index... ). I know there are implementations of this idea for Windows (Heck I even built one when I was learn shudder VB6 back in the day) but not a one I've seen is worth the effort of finding it.
