I have two macs (800MHz 17" iMac; 12" Rev. B PB) running 10.2.8, and will be take the Panther plunge soon, although I may wait to 10.3.2. Are there advantages to doing a clean install rather the upgrade option? Will it be more stable in the long term? Thanks in advance for your comments. If this is something that has been beaten to death already, my apologies.
