Just got Panther at the Apple Store located in Valley Fair. I just finished getting it installed and updated right now. I'll have to play with it for a little before I get a good feel for it to write something up. But initial reaction: Cool! Lots of cool little changes all around, but still need to explore to find out really cool stuff. The boot time on my iBook 600MHz Dual-USB has decreased with Panther, so that's a pretty good improvement already. More to come!
