Confuscious say: Man who dies with most toys wins!
If you only produce output with an A4/letter/legal sized printer ignore the blandishments for going super mega pixel unless you consistently and savagely crop your shots.
In this situation the wise buyer goes for the ancient (18months old!!) top of the line camera from the manufacturer providing top quality optics and ccd and which was an award winner at the time.
Your monitor and printer cannot resolve, display or print the number of pixels in your files. Everything else is techno willy waving.
There's a pretty good chance I've got more full colour magazine covers in my portfolio than anyone else on this forum. I've used digital for more than 13 years. I've used ccd based equipment since 1974 - that is not a typo!!! 29 years of digitally produced images. Not braggging - just putting my comments in context.
If you want the latest toy that's fine - as long as you know it's for bragging rights only. You will never use all the facilities or resolution unless you win the lottery and print A3+ format.
