Well, thats what Itanium oppologists (this isn't directed at you) keep saying; there is a time to just admit to customers or potential customers that the idea seemed great on paper, by in reality, it never delivered due to the complex nature of it.
I think, personally, what really killed it was the stopping of Solaris for Itanium coupled with Microsofts decision to have a very niche concerntrated Itanium version of Windows that wouldn't have all the same bells and whistles that would appear in the the x86-64 version.
Personally, if I were Intel, I would have gone with an ISA that had a chance - the archiecture you can change, modify, and turn up side down if you want, but once you've chosen you're ISA, you're stuck with it.
SPARC would have been a good one - don't take SUN as a benchmark for what can be accomplished; a Intel architecture, SPARC ISA (along with VIS) bolted onto the top, coupled with Intels raw economies of scale, it could have turned out to be quite a nice product - throw that on an EFI motherboard, and bobs your uncle, you'd have a processor with an openstandards ISA, 64bit from the ground up, a well known ISA with good compilers available for it, a large ecosystem in the way of software vendors, it would have been a massive win-win situation.
an OS hasn't been written to take full advantage of itaniums full feature set.
What features would that be? I don't think the OS can do much for the Itanium; it's the compiler that has to do all the hard work of exploiting instruction level parallelism. The OS is more critical on architectures that rely on thread-level parallelism, e.g. Sun's Niagara.

They are quickly reaching the limits of the given architecture. Hence the reason IBM is starting to push CELL. itanium is new an fresh and has some room to flex not to mention from my understanding an OS hasn't been written to take full advantage of itaniums full feature set. HP-UX V2 is basically a port same with Redhat not fully optimized. x86 is long in the tooth and 64 bit x86 albeit somewhat new won't last.
Alpha was great technology that was owned by a bunch of dumbasses(Digital) that couldn't market it properly. itanium is in a lot better position.
