Are we going to then see the images on a curved screen? or curved print? At some point, the image still has to be flattened... distortion will occur (see the multiple different variants of ways to project the surface of the earth onto a "2D" map surface - some are accurate at the equator, some are accurate at mid-lattitudes, some are accurate at the poles, none are truly accurate).
I have had thoughts about this curved sensor for a long time. (like was posted earlier - the eye is, after all, a curved sensor with a curved lens formula) It makes great sense for image capture... take the flat sensor issues out of the optical formula, and you solve many of the focus, CA, etc etc uniformity problems. IF the software side of things can correct for the distortion in a very good/non-destructive way (no pixel interpolation/stretching in order to display them in 2D), then maybe this would be a good technology to develop.
What would the bokeh look like? can....you.... imagine? The BOKEH!!! after all, that's the only thing that matters, right?
