I love the new look as well (although it did take some getting used to) and agree that Leopard is probably going to be a combination of Platinum (Mail 2) and "Burnt Platinum" (iTunes 5). I'm just surprised Apple didn't update Quicktime 7 to match iTunes' new look, seeing as it's out of beta on Windows and had a small update on the Mac yesterday. Oh well, maybe in 7.1. iLife (and iWork) '06 will probably make their intentions for Leopard and future apps' interfaces even clearer.
I just wish that they'd left the volume control bar under the play, next and previous buttons. After seeing it there for so long, it feels so awkward beside them.
And, after using the new update on Windows, the iTunes menu bar looks very awkward positioned where it is on the window when not using iTunes full screen.
Oh, and that story about Brushed and his agent was hilarious.
