After installing a bunch of Linux distros (the main popular ones) I wondered if there were any I missed or any interesting operating system developments like netbook OSes that I could demo or something. So far I have BeOS (Haiku alpha 1), Debian, Fedora, LinuxMint, Mandriva, openSUSE, Ubuntu and Windows XP installed. Why? I'm curious and I like to keep on top of developments in Linux distros and general non-Linux OS releases for a more informed experience. All the virtual hard drives are on an external USB hard drive which seems to work quite well (I'm not too worried about speed there).
So, is there anything I'm missing?
