ahh yes but for how long JJ ? old macs will only start drying up and the next Sam boards and X2000 etc will only get quicker...besides for everyday computing who gives a crap about the fastest 5+ Ghz machine really
That makes an awful lot of assumptions about a lot of things, for instance that the huge costs in developing even "mid range" performance hardware with an exotic PPC such as the one in the PA6T for starters. It assumes also that the X1000/460 ever sells enough to recoup those costs or that PPCs that are in any way useful to the desktop are still available, consider that the PA6T being used now is basically warehouse stock that will never be replaced.
