Having tried preupgrade a few times since it came out I always become a 
bigger fan of using Yum and now it's the only way I'll do an upgrade:

       http://fedoraproject.org/wiki/YumUpgradeFaq

My biggest problems with preupgrade are:

- restarting after it has downloaded everything is a brutal reboot, not a
  nice shutdown/reboot - that's icky

- restarting manually, like "I'll reboot after" , doesn't load the new
  installer kernel so you end up back where you were before (and wondering
  WTF?) unless you edit grub.conf to use the installer kernel

- the installer needs at least 768M to run upon reboot, something it
  doesn't mention two hours earlier when you start the downloading

- the installer needs a much bigger /boot than you need to run with after
  so you hit the too-small gotcha

The only benefit I see to preupgrade is that you can work while it 
downloads, but if you don't know the gotchas that becomes moot. With Yum 
you clean up a bit first (as you should before preupgrade) then download an 
RPM for the release you want, and then yum update sees you're a release 
behind and starts downloading. When it's done, reboot and clean up. Very 
tidy and so far for me through a dozen server and workstation upgrades, 
much more reliable than preupgrade.
