I remember the change from 8 to 16 and 16 to 32 bit processors. There were many and varied problems mostly related with applications and software/drivers some of which have still not been overcome. Thinking or thunking will have to be backwards compatible this could turn NT/XP/2000 back into Win3.1 with knobs. If you put this into context with processor design (threading technology) and the fact that multi-processor systems are on the way up, even without any advance in the technology (but plenty of advances in motherboard design's) what's the future? I’ve just heard on the news that the biggest internet processing company in the world is at the mercy of the US banks, by January 2003 when it's loans are due (they can't make the repayments) is is deep trouble. This company just about run's the world’s www sites and related traffic including more than 50% of e-mails worldwide. All CPU manufactures must consider themselves now at risk; as have been other (larger) component manufactures who have large R&D programmes. Don’t lets argue about which is best Intel or AMD CPU? It might well be the case that within the next few months both will be bust. Where will all your “who’s best” arguments be then? Also consider where these companies actually manufacture their hardware, some of these countries are very unstable now. The years of dramatic developments in worldwide computer hardware design and developments (40 years) look to be about to stall for at least a few years (five), buy your cheap CPU’s and memory now costs, are set to zoom upwards dramatically. What do you think?
