My experience with VMware's software started with their first release of VMware workstation back in 1999 (or 1998?).
Back then it was possible to hack their evaluation license file to change the expiration date. Ah, the good old days...
Now, they still make great virtualization software, and their latest coup is to release the ESXi standard product for free.
The linked pages below document some of my experiences with VMware products and contain tips & tricks.
