NO, its NOT the best platform for running OS4, in fact the X1000 outperforms the X5000 in several areas.
Its the best you're allowed to buy.
True. It's a real shame that supply of the PA6T CPU at an acceptable price was killed when Apple bought up PA-Semi. At least Freescale (now NXP) committed to longer-term supply of the P50x0 and P10xx. They're not desktop class CPUs (which are hard to find in the PowerPC world), but they're available at an okay price.
Progress....right? And it only to 12 years, but were getting better, after all Tabor will move us from 64 bit cpus with a standard fpu (albeit without AltiVec) to a 32 bit cpu with a non-standard fpu that operates at less than half the speed of the G5, and only slightly more than half the speed of the X5000.
People have been asking for a low-cost low-end board; this is it.
And people think this will be adequate. Personally, a new release with performance that might not even match an Eyetech AmigaOnes is not progress to me.
You don't honestly think that it'll be slower in general use than an A1-XE do you? Sure, the A1-XE G4 had altivec, but it's data buses (memory, AGP, PCI) were all very slow compared to Tabor.
