I definitely see the market for a good mac emulator. Its an awesome way to get the mac onto a pc for the windows user to take a look at the mac without having to invest in one. There are lot of PC users who would feel more comfortable with it on their PC (small investment) in order to test it out. Also, it would make teaching mac-based classes easier. If you have a lab of PCs and want to teach someone about iMovie or do a tutorial on the Mac OS, you can do that with existing hardware.
