All of these things are true, but none of them are very relevant to the original point being made, which is that the Power4 (and its successor, the Power5) are leading the high end server market both in terms of performance and shipments. SPARC would be second (in terms of shipments, but not performance), and Itanic has 0% market share (its performance is not bad, but it can't beat Power as a server chip, and there's little software for it, so it's no wonder that nobody is buying).
Despite great resistance, even IBM cannot ignore Itaniums growing momentum. With IBM's new Itanium servers and blades in the works, how long do you think it will remain at 0%. Xeons started with 0% of the high end server market. Then they started beating the competition at TPC. Then IBM, HP, Dell adopted them. Similar story happening with Itanium.
Intel based supercomputers more than doubled this year on the top 500 with an Itanium 2 system at #8. And the next revision is on the way.
Out of one corner of the mouth Power4, 970, out of the other, Itanium. IBM isn't stupid.
As for software, you have 64-bit Windows and Linux, SQL, Websphere and scientific software optimized or being optimized for Itanium, even ATI has Itanium optimized drivers. Anything else you can write or have written.
Like I said, G5 is great for Macintosh, but 32-bit x86 and Itanium have huge price/performance growth potential. Intel would be idiots to go 64-bit at the desktop right now. What would they gain?
Tongue in cheek: Don't be so hard on the x86 architecture, it made the mac what it is today. (AGP, Hypertransport, DDR, PCI, IDE, SATA, USB, etc.)
