Actually it's a one track spelling. But I won't get into the details of both meanings. Like their and there. They both mean different but sound the same. So it's not one track, it's being smart and knowing proper grammer :-D And on G5s, yes that will be great. I already own 350MHz G4 PCI Graphics and I'm planning to get a Plutonium Pow... I mean Titanium PowerBook. I will sleep with it every night.
