Under XP I have used VirtualPC which I find very very very easy to use.What is the best equivalent to do test installs of other Linux desktop oriented distros or even (shudder) Win operating systems ? The support for a graphic screen is a must of course and also some "virtual networking" enabling FTP/HTTP from the virtual machine.
VMWare is not an option for me. I'd love to know about your real experience. Thank you, Bob
