No audio inputs
According to the Tech Specs on the Apple site (http://www.apple.com/uk/macbook-pro/specs/), the headphone port includes:
- Support for Apple iPhone headset with remote and microphone
- Support for audio line out
which is exactly the same as my 2011 Macbook Air 13"...
So whilst there's no dedicated audio line in socket, it's not true to say that there is no audio in - for instance, it would be fine use an iPhone headset to make a Skype call on the Retina Pro...
