My last digital SLR was a Nikon D70 with 6MP, and my Pakon gives me roughly 6MP scans from 35mm film. Both produce great 15x11" prints which I've had hung around the house for years. My Epson P400 (and most other Epson consumer and semi-pro devices) prints at roughly 240dpi, which means the maximum file size required for a 16x12" print is about 10MP.
I can see how it would be handy to be able to make tiny crops, but in general, why would a photographer ever need a 60 megapixel camera? What's the point, when it will inevitably cost more money, require double size memory cards and the images will gobble up double the hard disk space compared to a 24MP camera?
