I was wondering if anyone has had good experience with the 6.1 version of VPC? I know the Windows 2000 is apparently the best to run but I heard the VPC 7 is also great. I noticed the 6.1 is considerably cheaper so I was hoping it would still be fine on my ibook G4. I basically want this to play my old pc games like Roller Coaster Tycoon 2 and others.
