Hi, I've recently installed the .3 upgrade (from .2) on my almost 4-month old iBook G4. Ever since then I've noticed a decrease in speed, slight but noticeable, and I've had my first error message thing (hold down the power button 'cause you need to restart). I repaired the permissions via Disk Utility almost immediately after installing the upgrade and I'm about to run XBench (I got just under 80 before if i remember right). Anyway, I'm concerned about the speed. Is there a way to revert back to 10.2 without loosing all my data? And has anyone else noticed this? Many thanks, Matt.
