I've heard some things floating around MR that Panther improves battery life, and improves performance. Now, before I start telling people that William Wallace is 8 feet tall and wrestles bears for fun, I'd like to get a little confirmation from those lucky enough to have used Panther to confirm that the Panther rumours are indeed true. If it DOES improve battery life, can you tell me by how much? And if it improves performance, is it anything to get excited about. I have heard ridiculous stories about iBook notebooks getting 3.5 hours of battery life with Panther installed, when they used to get 2.5 hours with Jaguar. Sounds looney to me, but I just want to know. Hopefully my "up-to-date" copy of Panther actually ships on the 24th and everything is true.
