First, bear in mind Apple consciously modeled itself on Sony (but, as it turns out, not slavishly).
Second, Apple tends to follow its own standards (e.g. iPod dock connector, magnetic power cord thing). Sony not only uses proprietary interfaces, it's inconsistent about them. E.g. At one point they had a range of MP3 players none of which used the same connector as another or earlier generation products.
