J. C. de Oliveira (08.26.13, 6:53 PM): I have a Lytro camera for a few months now. It is interesting, but somewhat limited. I have been using it less than I thought I would, but I did enjoy to spend a day taking pictures of insects and flowers in a botanical garden in the neighbor State. The perspective shift is quite interesting. The camera has wifi connection built in, which allows an iPhone to pull the pictures and post them while you are on the go. I am awaiting some remote shooting option to be implemented. That would be awesome!
With regard to Steve Jobs, what I read was that he had plans to have the refocus setup available in some future version of the iPhone. I do not remember where I read that though, maybe it was in the Lytro forums.
