Please note that 300 dpi is meant "at reproduction size".
You can also get satisfactory results with 225 dpi ... and there is 
at least one very nice product (commercial) "PhotoRetouch Pro" with 
which 200 dpi is just what you need, they say, for 150 linescreen. 
The best thing to do is try different dpi settings and see what suits 
your needs.
Many factors will affect overall image quality; dpi is only one of 
them, as Craig Ringer points out.

Again, I agree with Craig. There are many things to be considered 
when it comes to image quality.
The MegaPixels value is for the most part about the "size" of the image.
The more pixels the larger the image.
If you intend to reproduce images at no more than letter-size, then 5 
MP is just about the minimum.

That could lead into a very interesting discussion! Basically, hiding 
low resolution is, imo, rather difficult if at all possible. Of 
course, you can "create" a totally different image with all sorts of 
filters... but we're definitely talking about different things here.
