Zip, none, nada, zilch problems
Haven't had a problem yet on either iBook G3/900 or 20" iMac. Both, especially the iMac are much faster. I did an archive and install.
I did spend about a half hour on each machine repairing permissions, run cron jobs, deleted all kinds of crap, caches and restarted before the upgrade.
First impressions - Spotlight will be very useful, Dashboard is just eye candy at this point, Quicktime HD videos at Apple's site are amazing and Safari does a nice job with RSS feeds.
