This is something I'm personally very interested in. I've always appreciated the Single Sign-on approach but hate the concept of giving Facebook or Twitter all my usage data.

If Apple is really able to keep things private this will be awesome! It will also make our AppleIDs more valuable, but at least it would help mitigate some security issues. Really it would be a tradeoff, but at least one that is in the end likely to be better for the average user.

The random generated email address is my personal favorite. I use a non-apple email address for my AppleID so I love the idea of not having to give it out to signup for a site. It also means I'd be willing to signup for more sites that I currently refuse to for the reasons of privacy.
