I smiled after reading this post. It reminded me of the fact that in our office, designers use my laptop to test web sites on Microsoft Internet Explorer 6. We have two guys doing the designs, and one of the uses Windows Vista, which runs MSIE 7. Another one uses, I think, Windows XP, but with MSIE upgraded to version 7 too. I heard it’s possible to have several versions of Internet Explorer running on the same Windows installation, but nobody around here knows how to do it or cares enough to experiment.
But the funniest thing in this whole story is that my laptop is running on Fedora Linux.
