As most of you probably know, iTunes has a different brushed metal theme than the other brushed metal apps (Safari, iMove, iPhoto...) I thought they would give iTunes the new metal in 4.0, but I just investigated and they didn't. I wonder why?
Probably because the new iTunes is based pretty closely on the old iTunes 😱
If they want to keep 10.1.x compatibility they can't use the 10.2 "Textured Window" API like the other iApps have done recently. Eventually they'll go 10.2-only, and THEN they can get rid of 10.1 legacy code and use the "standard" metal look.
