Ahh, I wasn't aware that they did that.  I interpreted the offset 
microlenses as not being centered directly over a pixel, but still funneling 
in light into just one pixel.  Thus, enabling light to come in at more 
oblique angles and still be captured.  I drew an ascii diagram, but I'm sure 
most everyone's mail client will mangle it, unless you have monospaced 
fonts.
