> VMWare was around since the late 90s - but at that time you typically had a computer with a single thread. If you were splurging, a system with two CPUs (two threads). Even a moderately load intensive VM would make working on the host system annoying.

VMware released their first product in May '99. Where you thinking of Wabi?

99 still counts as late 90s. I only remember that I was playing with it before 2000.
