Windows "It's the end of the line for 32-bit operating systems, Microsoft has proclaimed at its annual Windows Hardware Engineering conference After the software giant has gotten over its hangover from partying like it's 1999 with the release of Windows Server 2008, it will have one last 32-bit hurrah with a 'release 2' update to Windows Server 2008, and that'll be it. 32 bit CPU: if you have one, learn to love Vista - you're stuck with it.There will be no more versions of Windows - on desktop or server - that will work on 32-bit CPUs like Pentium 4 or Core Duo."

Kernel moves ... user can stay 32-bit

As I understand it, this just means the post-Vista kernel will be unconditionally 64-bit. It's quite easy to run 32-bit apps on a 64-bit kernel - Windows uses WoW64, Linux just needs 32-bit libs (usually ia32-libs or something). MacOS is natively 64-bit on newer processors, but all user apps run 32-bit.

In this case, 32-bit compatibility is easy. The only things that HAVE to upgrade are drivers, and those already have to be 64-bit for Vista. Honestly, this isn't a big deal.
