On their
MacBook Pro page they even have a battery video to show the difference.
Apparently because I have Quicktime 7.6.0 instead of 7.6.2, I can't watch that video. And I don't really feel like rebooting to bother. (I really don't understand why upgrading Quicktime necessitates a reboot.)
It gave me the same annoying message, but when I canceled it I was able to see the video anyway.
That doesn't piss me off nearly as much as the Windows auto-updater that refuses to remove Safari from the install list.
