After reading how slow VirtualPC was to install and run, I was afraid of being very unhappy with it. (I have a Mini 1.5Ghz w/ 80 gig HD & Superdrive.) However, I had the program along with the included Windows 2000 installed, configured and running in under 45 minutes with no problems at all! I then installed my one PC program that I need (that doesn't exsist on Mac) along with it's large database again with no problems, and in no more time than it took to install on the actual PC. The program is a very basic database w/ search and cross references, but runs just as fast as I was used to. The included Windows programs(pinball, etc...) ran fine as well. Don't fear VirtualPC if you need it- I got it off Ebay for $100 less than retail.
