Lockdown
It looks like Apple is really closing off development choices for the next gen OS for the iPhone and iPad - John Gruber quotes the new developer agreement:
Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited
That certainly puts John McIntosh in an awkward position.
I guess they really, really want to completely control the user experience...
