That's true too. I've mostly adopted a "wait and see" approach to this whole thing. Some people have assumed the PA6T is necessarily a G5 slayer and thus ready to stomp all other PPC machines, without considering that the PA6T was designed for a different market. Where it probably will smash the G5 is in performance per watt, but all considered, that's not saying much.
I've never done any testing of this myself, but it looks from benchmarks I've seen like the G5 isn't actually much of an improvement in terms of performance-per-clock - more just that it broke out of the 2GHz barrier Motorola couldn't get the G4 past.
One thing that has come out of this, at least for me, is the realisation that the old PPC machines perhaps aren't quite as slothful for everyday use as many assume. At least if the lame benchmarks were any indication of single core performance.
They really aren't. Memory throughput and disk access can be a limiting factor, depending on the machine, but overall (Flash/fullscreen HD video excepted) they're surprisingly capable. TenFourFox on a 1.25GHz G4 runs noticeably better than the equivalent Firefox version on my 1.6GHz Eee, f'rexample.
The industry just keeps us buying the you-need-more-horsepower myth, that's what I say...
