Cameras and megapixels
In my Uncle Mark Gift Guide & Almanac I advise against buying a given digital camera just because it promises lots of megapixels. I use a two-megapixel camera and it works really well... better, in my opinion, than the five- and seven-mexapixel cameras out there. (Read the guide to see my recommendations.)
A recent column by David Pogue (one of my favorite tech writers) supports this idea - as he's done in the past - with a little mythbusting. From Breaking the Myth of Megapixels
The Megapixel Myth... goes like this: "The more megapixels a camera has, the better the pictures."
It's a big fat lie. The camera companies and camera stores all know it, but they continue to exploit our misunderstanding. Advertisements declare a camera's megapixel rating as though it's a letter grade, implying that a 7-megapixel model is necessarily better than a 5-megapixel model...
There are some reasons to consider a large-megapixel camera, and Pogue rightly covers them, but they're secondary for most people.
