Maybe it's because some software is not available for 64-bit systems,
and the devs won't provide what I think is called multi-arch so that
32-bit programs run on the 64-bit system. It's a trade-off--you can have
a distro that supports 32-bit apps on a 64-bit system, but then you have
to put up with all the BS that that distro imposes on you.
