I am one such, here:
http://www.finetunedmac.com/forums/ubbthreads.php?ubb=showflat&Number=2081#Post2081The old G4 on OS9.2.2 is behind me as I type on this iMac. It's a real workhorse and I have nothing but complete respect for it.
The old G4/OS9 does half the work; the iMac OSX does the other half. It works for me!
