iPhone is now the number 1 smart phone in the US in just over a year. Revolutionizing the cell phone market is fait accompli.
I do agree with Woz's coments about the platform being locked down, but I don't think this is going to be a permanent condition going forward. The platform is still in it's first year. I expect that Apple is going to loosen up quite a bit after they feel the OS/platform becomes mature enough. It's actually a smart way of doing things because they keep a tight leash on the overall platform development direction in the formative years.
But let's all watch how Android unfolds. It might quickly turn into a trailer park for crappy code, or it may quickly emerge as a highly stable and popular platform.
It's good to know that developers will have a choice between the two platform development strategies. They can choose the highly managed Apple iPhone environment with it's tight ties between the code and device or they can choose the much more open Android solution. Let's all judge this by who delivers the most functional and reliable smart phones.
