It's Fedora 8 GNU/Linux running VirtualBox on a dualscreen setup with only one screen configured to be the "desktop" with panels.
My right screen therefore has all its pixels free for anything i want "real" full screen.
I've configured this at work and put Windows XP in a VirtualBox as "full screen".
Really all the designers, web-designers and even the tech peeps thought i was the only one of all people that has 2 computers just to run any system at will.
I just said "oh the Mac comes soon as well"
So maybe an idea to put a dual-screen mac on your place and run Windows and GNU/Linux on those just to poke soem eyes out?
