Hmmm,

their claims about the performance overhead of commercial packages might
be a bit outdated. I am running Win2K, a Linux and a FreeBSD on my
Notebook ... all three in VMware 4.0 hosted on a very bare Win2K ... I
don't see much performance loss.

It's a Compaq Presario 1525US - 2.4GHz P4, 1GB 266DDR Memory, 40GB Disk
and ATI Mobility Radeon 7500 32MB. Was a "clearance" last year already,
so nothing really fancy.
