"Linux enthusiasts love to hate Windows, and Microsoft often disparages the very concept of free and open-source software. But if you're running a high-end server, you probably stay above the fray. Many Unix users still look down on Windows and Linux, seeing one as a bug-ridden overlay to DOS and the other as something hacked together by amateurs.

"Both perceptions are out-of-date. Linux and Windows are set to challenge proprietary Unix architectures that tie a particular Operating System (OS) to a particular microprocessor. The main impetus isn't coming from Microsoft or the open-source community, though they're happy to participate. It's coming from chipmakers Intel and AMD, which hope that their new 64-bit processors will commoditize high-end servers in the same way that open PCs replaced proprietary microcomputers twenty years ago.

"The roadmap to 64 bits isn't straightforward. Intel Architecture 64 (IA-64) isn't compatible with 32-bit x86 code, making upgrades harder. AMD's x86-64 is backward-compatible, but won't run IA-64 code. For the first time, Intel and AMD are moving apart, and neither uses the same approach as current 64-bit processors..."
