I assume you're using 99% in a "wave your hands" sort of way. I very
much doubt that only 1% or less of the market is Apple Intel systems
which I would consider to be essentially 64-bit in many respects now.
And when a majority of those system move to Snow Leopard .... which
seems likely given Apple's aggressive pricing ... they will probably
be as 64-bit as you're going to get a system with an x86-64 processor
to be.

I'm not sure what the thinking is over at Microsoft, but it looks as
though they're also moving in that direction. The Windows 7 install
media will apparently contain *both* the 32-bit and 64-bit versions of
Windows. They won't be sold separately any longer.

None of this will immediately change the fact that a majority of the
x86-64 systems out there will *still* be running in 32-bit mode. I'm
just saying that a lot more than 1% of them will move to 64-bit mode.

It took a long time to build up momentum, but I think from this point
on the switch over is only going to move faster.
