I think sometime down the road... maybe a couple years... apple will go the 'microsoft route' and just start licensing the Mac OS, seeing as how it can now run on PC's and that's all a mac really is now...
Apple did that once before, back in the 90's. Knew an outfit that was using the Umax clones and they were none too happy. The clones had some definite quality issues. I don't see Apple going the licensing route again.
