I have to LOL. I was using virtual desktop software almost 20 years ago on a 286-based computer under Windoze 3.1. The package I used was PCTools from Central Point Software, but there was also Norton Desktop. Symantec eventually sucked up both and then shut them down when Windows 2000 came out and kinda but not really made them moot. Who knows, maybe someone will invent virtual computers one day. (oh yeah, IBM did that 40 years ago didn't they?)
