iPhone: don't think of it as a computer
Via Rafe Colburn I just found a NY Times article that confirms Apple will tightly restrict what apps are allowed on the iPhone:
Steve Jobs: "I donât want people to think of this as a computer [...] These are devices that need to work, and you canât do that if you load any software on them [...] That doesnât mean thereâs not going to be software to buy that you can load on them coming from us. It doesnât mean we have to write it all, but it means it has to be more of a controlled environment."
Controlled environment? You mean like a Java VM? Probably not. I suspect what Mr. Jobs means is that 3rd party software vendors will have to pay Apple for the right to develop software for the iPhone, but details of that plan have not yet been worked out.
