The atmosphere here is interesting. There was a lot of energy and interest on Monday right before and after the keynote, but it seems to have dissipated since then. Even the number of developers hanging around seems to have decreased since Monday!
As for information about Panther or the G5, there's not a lot I can say, really.
Apple has stressed (on several occasions) that unless the information is already public we're to keep it under our hats. Most of the information is targetted at developers anyway; I doubt most users would find it useful or interesting.
I can say, though, that's the weather here in San Francisco is wonderful. I'm not looking forward to returning to Ontario and dealing with the heat wave there.
