But that silicon isn't getting any cheaper, as far as I can tell.
I don't know what a 4x5" slice of silicon would cost. Probably a number that we associate more with space shuttles than cameras.
Maybe there are other semiconductor technologies in the works. Would be nice if this stopped being a hurdle.
