Apparently, Windows 2003 is the successor to 2000, and 2008 further
still. Hence, it should be no huge surprise that they are dropping
support for 2000 and 2003. There will be no further service packs for
2003 beyond SP2 (and it supposedly still has the DPMI limit bug which
can't be fixed via registry, sadly enough).

I think Geoff Chappell proved that Windows does support PAE, even in
home versions (for NX protection ?), but even if it wasn't licensed
where it's disabled for home users, you still need special drivers for
it. Apparently MS thinks PAE is inferior to 64-bit, so they aren't
fully supporting that.

It seems MS is pushing heavily towards 64-bit as their future (which
also needs separate drivers). According to Wikipedia's 2008 article:
"Microsoft has announced that Windows Server 2008 is the last 32-bit
Windows *server* operating system." If that tells you anything.
