"All you guys have to do is write your own code from scratch, and make the buttons do what we need them do to.
You know what we need, so stop posting to forums and worse and do something meaningful: write new code that changes photography. Write your own Nikon or Canon camera OS, and heck, you can sell it; just don't copy any of Nikon's or Canon's code. I'll even help you define it, and help you sell it.
Would I pay several hundred dollars for "The Photographer's OS" for my D800 or D4? Absolutely!"
