[citation][nom]hixbot[/nom]Are you mad? Do you know how many 32bit CPUs are in use right now? Why would MS ignore 32bit hardware and all those sales? I'm running Windows 7 32bit on a Pentium 4. Performance is great. If you had your way, I'd be stuck on XP.[/citation]
Did you ever run Vista on that machine? If Microsoft had set the bar earlier, you wouldn't be talking about Win7 on your P4.
I agree Microsoft, a software vendor, would be foolish to ignore 32-bit processors. Still, it's more Intel's fault for continuing to produce 32-bit processors so long after the 64-bit technology existed (maybe they were upset Microsoft chose AMD's implementation?).
I think Microsoft could have easily shifted the market to 64-bit, if Intel would have played along. If Intel had simply been including 64-bit in most of their processors like AMD was, Intel would have happily done so (you think Intel gives a crap about your 32-bit P4, they already got your money for that processor). Remember how Microsoft had to revise their Vista-Ready/Vista-Capable marketing because Intel's GMA chipsets didn't have the graphics power to drive the Aero interface (led to a lawsuit if I recall)? Intel (and OEMs like HP) moaned and complained that too many of their offerings wouldn't be Vista-Ready, so Microsoft created Vista-Capable, and Intel was able to continue selling the 5-year old crap they couldn't bother to modernize. Imagine the uproar from Intel if Microsoft had necessitated 64-bit processors on top of that!
