Well, for a printed photo to look really nice, you want to go with a minimum of 300 pixels/inch. My 8mp camera produces an image of 3456x2304, which is just about exactly 8x10 at 300 pixels/inch. When I want to go any larger, I have to sacrifice quality. My 3mp Olympus was great for 5x7s, but anything bigger started to look grainy unless I proceessed it with some fractal-based photo enlarging software, and even then it wasn't perfect.
Another advantage to high-megapixel cameras is the ability to crop the photo quite a bit, but still end up with a print-worthy image.
My first digital was a 2.1mp Olympus C-700UZ with 10x zoom, which was a great camera despite the low megapixels. I then upgraded to the newer 3mp Olympus C-730UZ, also with a 10x zoom, which I used until recently... I got a bonus at work, and used it to buy an 8mp Canon Digital Rebel XT. This digital SLR is
awesome, though it will take me some time to master its features.
