MSN, I agree it can give you lots of advantages, but it doesn't replace a second CD-ROM. It depends on the use. Each image takes more space, so you don't want everythign on VCD either. IT is a lot faster to read from a VCD that from CD-ROM thought.
Basically only to keep your most used appz (or games) that run from CD and take time reading.
About the VPC, where can I find it?? I would like to test it. It is from M$?? IF so, maybe I have it with the Technet CDs, right??
