That's a amusing coincidence since at least some people think ia64 will end up the same way the i860 did :-) In the past I did always advocate things the way you are right now, but these days I think I've been wrong the whole time and Intel on x86 is doing the right thing. They do everything in hardware and this makes the software so much simpler. Sure, there's a lot of architectually inherited complexity in the x86 family, but their engineering priorities mean there is so much other stuff you simply never have to think about as a programmer.
