I love your sandwich but not so much your comment, but you are correct. In my defense all I can say is that this thread was started when 10 MP was the standard entry level which has since been eclipsed by 12 MP. IMO there is no real difference between the two anyhow and anything 10 or above is more or less the same in practical terms.
These days 12 MP is the norm, and whether or not you are looking at 10,12,14 or 19 MP, the focus(sic) should be on getting a camera that suits you. Unless you plan on making poster sized prints, the resolution is really beside the point.
However, you are correct in that this thread appears to be about 10 MP cameras, so I take back everything I said except for the part about the e-520.
