Being able to address more than 4GB of memory directly and having a
sane number of cpu registers to work with (x86-specific, mostly
irrelevant in ppc land, ppc32 isn't register-starved like ix86) are
certainly more than just theoretical advantages. Granted, a lot of
desktop users don't need more than 4GB and its taken some time for
applications to be updated to take advantage of the increased register
space, but it *is* happening. Anything that relies heavily on
vectorized code (such as multimedia encoding/decoding) and anything
that involves a lot of encryption work (VPN, WEP/WPA, disk encryption)
benefits from the increased register space (assuming software is
updated for it, that is -- which is the case for a good amount of open-
source software).
