OMG we get that you don't think x64 is worth it at the moment. That's fine. But please don't change the facts to suit your prejudices.

Technically Itanium is the only true 64bit processor since it contains no code to run 32bit instructions. It is used in servers throughout the world. It runs Windows server 2003/2008 and other 64bit server OS's just fine.

x64 (AMD64 or EMT64) processors are both 64bit and 32bit so that they can run both 32bit and 64bit applications and operating systems. These processors can run both server and desktop OSes written for 32bit or 64bit.

OMG you have to ask yourself, "If I have a x64 processor which runs both 64bit and 32bit applications, why should I buy just the 32bit OS when I can have both capabilities for the same price if I buy the 64bit OS?
