iTunes 5 is out, with support for Motorola phones with iTunes and the new iPod nano (replacement for the mini), new “smart shuffle” to control the repetition of artists, QuickTime 7, but best of all, a new interface.
The new interface is great, because it gets rid of almost all unused space with all the same functionality. Weirdest change is that the menubar, title bar, and corner buttons are all on the same level.
Also from what I can see it doesn’t put more limitations on shit or tell me that I can’t do something I used to be able to. So yeah give it a try!
