Actually, I was just looking to see if anyone else was experiencing this as well. I finally made the leap back to OS X after the 10.1 update came out (figured I'd give it another whirl). The first thing I noticed was that the startup chime was no longer working.
The second thing I noticed was even with the dramatic speed improvements, it's still a dawg.. and I'm not exactly running on a slouch of hardware either.. G4-500, 1 gig of Infineon RAM and 2x30 gig IBM deskstar 7200rpm drives, AGP Rage128Pro & PCI Radeon. Atleast it's somewhat usable now.
