You want proof that Apple is still a little bit OCD even post-Jobs? Pull out your iPhone with iOS 6 and take a look at the chrome slider reflection in the iPod app. Now, tilt your phone side-to-side. Yup, the reflection actually changes as the phone is tilted. Proof positive that Apple still has some OCD, detail-oriented people on its payroll.
This is just insane that Apple would actually dedicate the resources to do something this tiny. It serves no purpose other than to look good and replicate what would really happen. It's extremely impressive, but at the same time completely pointless. iOS 6 has many other more major features, so this isn't the whole reason for the update.
