I'm running a W2k Workstation VM in order to run a MS-only program I'm testing my Linux-based program against. I had created a 4Gb HDD for it (the default), but was running out of room due to various considerations. I merely ran a tool to expand the "physical" disk the VM sees, and ran Partition Magic within Windows to get it to see the whole new disk. Took about 5 minutes--including the install of Partition Magic.
Compare that to expanding a true physical disk, where I would have to go out (or order online) to get a new disk, tear the machine down, install the disk, configure Windows to somehow see both the original and new disks as one partition--I saved me (and my employer) hours and dollars.
It just an awesome technology.

Yeah but you need a gigabyte of RAM for each concurrent one, realistically.
