Just thought I'd see if anyone bought the upgrade. I picked up mine yesterday morning; two MacBooks and a MacMini later everything is running smooth as silk. Broke my color calibration, but not the software to redo it, so I just need to recalibrate. Everything else, including my almost four year old drivers for my Tascam USB recording device worked perfectly despite last being updated when 10.4 came out.
I haven't seen any rocket-ship speed improvements, but everything does seem to run a bit more refined. Maybe that's just me trying to convince myself the $30 was worth it.
