Just curious as to what people are finding the best option for running a virtual PC on their Mac are. I've got a 2013 MacBook Air, going to put anWindows 7 or 10 virtual machine on it. I'm tossing up whether I go with a bootcamp setup (this is dependant on whether the Mac can boot from an SD card?) or VMware or Virtual PC? Perhaps maybe parallels. Preferably a free option. What's everyones verdict?
