I've been doing some looking around regarding to this topic. Some peoples suggest emulators like Virtual X86 or GuestPC but I come to believe using an emulator will eat a lot of your system's resources since its running 2 OS at the same time. It will definately lag the Window's OS if you are planning to run that in the background. Especially when you use a iBook G4 like me with 768 RAM and install Window's XP as the 2nd OS. It lagged so bad I was forced to use a older OS of Windows so that it takes up lesser resources yet even though the OS loaded smoothly, most of the progs. lags so bad. So now I'm currently looking an alternative way. Some peoples told me about WineHQ but I haven't gotten any legit info regarding if it works under Mac OSX. Anyone know if works or if theres any other alternative to run Window's stuffs on Mac?
