I think that a more open Apple platform would be great. However, I do think in order to avoid the Microsoft problems there needs to be some kind of hardware certification on Apple's end. I mean if they are going to take the time to certify open apps for the iPhone surely they could dedicate a few resources to certifying more hardware as well. This would give all of the "power users" the reassurance that all of the hard work and money they put into customizing their systems is not going to mean they can never do a software update. I like Psystar's thinking, but I wish the first step towards a more open Mac had come from a more reputable source. All of the issues Psystar had in the beginning really made it seem like a shady operation which in my opinion damages the idea of an open Mac instead of promoting it.
