Apple's iPhone SDK: This is Brand New Big Sh*t, But

Barbarian's comments are on the mark. Developers were highly concerned that the SDK would be very limited in allowing outsiders access to the OS's core systems. The only way to grant total access (well, near total--I imagine) and not open up the platform for abuse was to control distribution. I think Jobs has finally learned from Gates's strongest suite--leveraging the intellectual power of outside partners.
