Very, very wrong, Karl. If you install 64-bit F7, all yum updates
will be for the 64-bit system unless only a 32-bit package is
available--in which case yum will update the 32-bit package where
necessary since the 32-bit RPMs will be placed in the 64-bit repos
(the repo maintainers are pretty good about that). That's what yum's
"$basearch" macro is for--selecting your baseline architecture.
If you install a mixed 64- and 32-bit system (e.g. "install
everything"), yum will update for both (you'll see ".i386.rpm" stuff
go by in the updater window as well as ".x86_64.rpm").

99% of all the stuff you want is available for 64-bit. If it isn't,
then download the source RPM or tarball and build it for 64-bit. If
you don't want to do that (or the source isn't available, such as
32-bit, 3rd party stuff such as Flash or Opera), then the 32-bit stuff
will run happily on a 64-bit system.
For example, I do virtually everything on 64-bit. When I want to watch
Flash, I fire up the 32-bit Opera, which talks to the 32-bit Flash
plugin and voila! I really only use Opera for that sort of thing...
otherwise I use Firefox 64-bit for virtually all other web browsing.
Saying "I will stay with 32 bit until it is no longer the most
popular" is also a bit weird. The only thing that's still popular and
primarily 32-bit is Windows. Mac OS/X is for Intel is even 64-bit.
If you want performance, go 64-bit. And you'll never even notice when
the very, VERY few 32-bit only stuff runs on the machine.
