What software and/or peripherals do you have that make you think you'd have a problem with Panther?
So many people are experiencing Panther with no glitches at all... I have it, and 5 other friends of mine have it, and not one of us has experienced any kind of problem.
My system runs faster on Panther, I have much better battery life on Panther, Panther is just plain enjoyable.
As for a 10.3.3 update, what would that do that 10.3.2 isn't doing already?
Remember, reports of problems aren't always due to Panther, and the reports are far outweighed by the excellent performance most users are experiencing.
