I've been thinking about the same thing since Google impressed everyone with their computational photography tech years ago. The software in DSLRs is really primitive in comparison.

Really makes you wonder what could be achieved by combining Google's computational photography algorithms with a bigger sensor and high quality optics. I'm probably not going to buy another high end camera, until I see something like that on the market.
