I was wondering if anybody has experience using a Psystar machine running OS X? Does Logic Express/Studio run well? Any issues with Firewire/USB audio or MIDI interfaces, or with the Audio/MIDI Utility? I'd love to get MacPro, but that's simply not in my price range, so I was thinking about an iMac. For a similar price, I could get a pretty sweet Psystar machine (and separate HDs for system/apps and audio). Any thoughts?
