AMD doesn't." Most businesses update their software base every few years. Some don't of course, and that's one of the reasons why IBM and others can continue selling legacy Unix machines for huge premiums, and people will buy it. Those same people are even reluctant to shift their software base to x86 - they are still using VMS or some other Unix OS that's outdated by at least a decade. These businesses are the minority, Dan, not the majority. The majority of businesses actually employ the Microsoft model of updating their software library every couple of years. They buy the newest Microsoft operating systems, the newest Office Suits, the newest SQL or Oracle databases, and the newest updates to their business apps, all over the course of 2-3 years - then lather, rinse, repeat - they'll do it again. This model is actually gaining share, since Microsoft continues to make headway in high end businesses. I also know this is true, since hundreds of high end software developers continue to make money by offering upgrades of their current popular titles. If businesses weren't upgrading their software, then these developers wouldn't be making money. Again, this is simple logic. The idea for Itanium (and even Netburst, to a degree), is that it fits perfectly with this increasingly popular software model. Intel isn't making businesses rewrite software - these businesses do it because they already intend to rewrite their software. Intel is simply making sure that their optimizations are included in the next version. But speaking of custom or proprietary code, if Intel will have trouble getting people to upgrade with their specific optimizations (as you seem to think), then how the frick do you expect AMD to convince them to program for x86-64? wbmw
