I would just like to point out that IA64 wasn't really a significant step up. VLIW is a good idea for DSPs and GPUs and whatnot, but for the kind of dynamic, branchy code that we all know and love, IA-64 was quite probably the only somewhat modern CPU arch that was actually worse than x86.
I'm not so sure about that. Modern IA64 compilers and systems are actually pretty damned decent. Though the fact that they are still only comparable to a monstrous, teetering pile of hacks and kludges (x86) is not much of a recommendation.
