I have to retract my comment above, I needed to run a win7 vm to do some design/vinyl cutting (the industry is Corel based) and while VMWare was fine at running Draw/printing, it fell over one one critical point, the USB implementation sucks causing jobs to stop mid cut, when you've got hundreds of glasses to etch that's not fun. Migration was simple after I changed the the HD setting in Fusion to single file and after re-activating Win7 Parallels worked without issue, i'll see the demo out before I buy but it's looking like it works better for my intended use.
