Are there not 50+ megapixel digital cameras out there? I recall reading about one last year in a photography magazine. The reviewer complained they captured too much detail or something
I guess some people like to call blur "artistic"
As for the digital cinema, I just read at Wikipedia that the main reason that it is used is becuase its easier for the distributor to apply copy protection :p
C. P. U. Its not a big processor... Its a series of pipes!
