David Pogue has a great summary of his work to expose "Breaking The Myth of Megapixels" in the February 8th New York Times. While I don't normally even try to cover the "capture" end of our Printing and Imaging biz, this piece was very much worth reading. Especially interesting to me is his description of his testing dilemma, which he describes in detail.
The essence of his point is that while "Megapixels" are touted among vendors and resellers as if they're a digital camera's ultimate metric of goodness, there are many more important other factors that ultimately make photos good or bad -- and that's just within the camera!
I also like how David using his blog responses to improve his testing!
