I find it very curious that the users who want low megapixel counts and high ISO seem to want to rubbish those of use who want/need exactly the opposite.
I'll never rubbish anothers needs because they are different from my own, but then I do expect the same consideration from others. Not so much here, where everyone is friendly, but on at least one Canon forum I used to frequent, the users want to draw blood.
My own work tends to be very methodical and slow moving. It makes much use of tripods, low ISO and slow shutter speeds, nothing like the photojournalistist or sports news togs need. Hence my wanting Canon to produce a D800 competitor.
