I've mostly moved my systems to Tiger, my last Panther holdout was a 2003 iBook G3 which recently had its HDD crash. Perhaps I will install it on a PowerMac G4 for testing. I have to agree that brushed metal was overused in Panther, hasn't aged the best.From February 2005 to mid-2008 (I believe) I was running it on a 1.8Ghz PowerMac G5 with 4GB ram. It also got installed to two PowerMac G4s. These Macs are my work Macs and are still being used (although they were upgraded years ago).
Until 2009 it was running on my TiBook 400. Then I got Tiger.
