Milhouse, it costs you credibility to say that 10.4 won't run on old hardware. I have it on a G4 and my wife has it on one of the very first G5s. Studies show that people run Apple computers longer, on average, than Windows computers. So it's likely that other people will call you on this. When you say something so easily disproven, prefaced with "Bollox!" it just makes me discount other things you say.
