Yeah, I looked at the article.
A few years ago I even considered buying a MorphOS computer (i.e. a Pegasos). That was before Apple switched to Intel when the PowerPC G4 and G5 were still expected to be upgraded again, and PowerPC was a "safe" architecture. I would have run Linux and MorphOS on the box.
But now I am totally on Intel.
I must admitt that I do not know all the operating systems mentioned in the article. But I think I will try them out, should they run on VMware.
IF ONLY I already had my two Sun servers and xVM. I could experiment much more.
