I know this is kind of a random question, but I had a thought - would it ever be possible to upgrade through all Mac OSes (from System 1 > 2 > etc. > 9 > X10.0 > ... > Snow Leopard/Lion? I realize different OSes have different requirements, but that would be easy to workaround by swapping the hard drive around in different computers including the Mac OS/X, meeting the requirements for each OS. If that is even possible at all, it would be VERY interesting to see what, if any old Mac OS elements make it up to SL/Lion. The reason I ask is because it's possible to upgrade Windows from 1.0 all the way through 7 (I know, I've done it before), and while I realize Windows is a different platform with different hardware requirements, I do understand it may be technically permitted, given the right hardware and someone who knows how to make it work. However, I could be very wrong, so if I am, correct me with facts!
