It does.

Perhaps /your/ desktop is doing "business processing", but last time I
looked, the big money was in home users, especially _games_.
We're talking billions of USD here. Almost everything home users pay money
for, benefits by 64-bit rewrites.

Encryption/decryption, games, encoding/decoding (playing movies full-screen
whilst doing some photo-batch processing), audio stuff, video editng,
picture manipulations It is all much snappier with 64 bits, and the near
future will be dual-core 64 bits, so you better not only learn how to
program efficiently for 64-bits, but to do it multi-threadedly as well, or
be a dinosaur.
