64-Bit Computing: A silent revolution? (alien.top)

I was recently reading Tracy Kidder's excellent book Soul of a New Machine.

The author pointed out what a big deal the transition to 32-Bit computing was.

However, in the last 20 years, I don't really remember a big fuss being made of most computers going to 64-bit as a de facto standard. Why is this?

XP 64 was a Server 2003 64bit edition for workstations. They had the same kernel as well. Oddball, but it did work well if you could find your drivers. I went straight to 7 64 after that.

Right,

Windows XP Professional 64bit is Windows 2003 kernel & something like the XP UI. This is why you can run in to software compatibility issues.
Windows XP 64bit (non-professional) was only ever available for Intel Itanium and Itanium 2 CPU's.
