All of our servers have been 64bit since '04 or '05?  Whenever the first
64bit multi-core AMD chips came out and were under $300.

For a server, the big reason to go 64bit is capacity.  While you might be
running on a 2GB server today, it's quite possible that you'll move those
disks to a 8/16/32GB server next year.  If you didn't go 64bit at the
start, you'd have to do the 32->64 move at the same time as hardware
migration.

(Just as a hypothetical "for instance" example.  May not occur frequently
in real life.)

For desktop use, sounds like we're finally to the point where you can run
64bit Linux on the desktop and stay functional (i.e. Adobe Flash).
