Making software better, especially highly complex apps like iTunes, is a never ending process that requires an almost fatalistic dedication. Seriously, it’s an absurd balance between delivering nuts and bolts functionality while trying to move the platform ahead across dozens of devices out to an ever widening horizon of new requirements and features.

That said, iTunes 10.1.2 (90.43MB) is now available and brings the following to the table:
— AirPlay to instantly and wirelessly stream videos from iTunes to the all-new Apple TV.
— Sync with your iPhone, iPad, or iPod touch with iOS 4.2.
— Security updates in this release

Yes, iTunes 10.1.2 for Windows (64 bit) (79.16MB) is also available if that’s the way you roll.
