The main reason Microsoft bought VirtualPC is as an emulation layer for backwards compatibility of legacy software in Windows Vista when they transition to the WinFS database-style file system. The Mac version just happened to be along for the ride. It'll eventually be dropped from their software lineup for Mac. There were lots of pirated copies of VirtualPC6 floating around on the internet. VPC6.1 broke the serial number hack that allowed the pirated copies to run. VPC7 added token support for the G5 processor with no AltiVec support and a "fix" for the G5 not supporting pseudo little-endian mode. It's slower than the proverbial molasses in January compared to VPC6 on a G4. There has not been one performance enhancement to VirtualPC since version 6.0 -- Chris ------------------------- PGP Key: http://astcomm.net/~chris/PGP_Public_Key/ -------------------------
