I have run Virtual PC 7 on my iBook and a 15" PowerBook from the current gen. The speed or lack thereof was more than a little frustrating, so I don't like using the program at all. Sometime next year I'd like to purchase an iMac G5. Depending on what the next update is like, my plan is to buy a refurb of the current generation at a substantially discounted price. My question is, would I notice a significant speed difference between the notebooks and the G5 with VPC? Obviously I can't expect it to be very speedy, but I'm really hoping a G5 would at least make it somewhat tolerable. Anybody who has experience please reply.
