Certainly, a typical desktop machine isn't going to see much advantage from running a 64-bit distro (whether it's Fedora or anything else), simply because most people don't need the extra address space, and wouldn't notice a few percent of performance difference one way or the other on most typical apps.
Indeed, since some popular apps (e.g. notlame) contain hand-coded 32-bit inner loops, the x86_64 versions can be relatively slow, because they currently fall back to generic C code.
That said, specialist users have needed 64-bit systems for years - ever wondered why Sun dominates the EDA market? - and now they have the opportunity to switch to Linux. Or at least they will once the ISVs pull their thumbs out, which should happen over the next few years.
On a final note, Ladislav says "Unlike Debian, Fedora doesn't offer a possibility to install the 32-bit part of the system into a separate, "chroot-ed" environment" as if this were somehow a good thing. The Debian approach to 64-bit support is suboptimal, since (a) it's incompatible with the x86_64 ABI and (b) it forces you to jump through hoops to run 32-bit apps.
