Virtual PC 7 was loaded on two computers in my home. One is a G5 single 1.8 with 1GB RAM and the other is an 800Mhz iBook with 384MB RAM. I then loaded Peachtree Complete Accounting on both and MS Office 2000. This is my first time using any Virtual PC. So after reading various reveiws at Amazon and in various magazines, expectations were not high. However, I was pleased with the response time and quickness of the product. In fact Peachtree runs "Virtually" better than it does on the Windows system at work. Interestingly enough, Virtual PC 7 runs much better on the iBook than it does on the G5. With the horsepower of the G5 I thought it would blow the iBook out of the water. Not true. It may be that VPC7 is "new" to the G5 processor yet and there are still bugs to work out. (After all, it is a Microsoft product).
Startup and shutdown of VPC7 on the G5 is horridly slow (almost 2 minutes each). Pack a lunch. The iBook startup and shutdown of VPC7 takes about 30 seconds each. Again, amazing!
Other than the minor G5 issues mentioned, Virtual PC 7 works fine. Would I buy it again, yes!
