I decided to see what Franz was talking about essentially saying lighter is better.
I downloaded
Iridium and have been trying it out for the past day.
I must say I do really like it. Iridium itself does not change iTunes 5 but seems to change everything else to a much more uniform look. Most closely resembles Mail. (Iridium comes with another app that will change iTunes but I have not done that yet. I still like iTunes 5 looks.)
On my PB, Mail does not appear as washed out as it does on our iMac G5. I may give it a whirl on the iMac since it is easy to restore back to the original Tiger look.
What I have noticed now that I downloaded Iridium, is that I like the apps that don't have margins on the sides of the windows. iTunes, Safari and Mail look much better to me than iPhoto, Addressbook and iCal which do have margins. Maybe that is what Apple should really change.
