But how does that accomplish a 130 MP? What's special about a scanner vs a camera that lets it do that?

Size. Scanner is 8"x10" or so. The actual DPI of the scanner is lower than a traditional camera CCD, but there is so much more space. Your exposure time is how long it takes the scanner to traverse a "page".

Focusing seems painful.
