Interesting read and I stand corrected regarding hardware binning; "This process is performed prior to digitization in the on-chip circuitry of the CCD by specialized control of the serial and parallel registers." as opposed to in the firmware after digitizing.
You got to wonder though if the increased read noise (4 reads instead of 1 read for 2x2 binning) would really register when performing a single readout per-pixel at the end of a long exposure; you certainly wouldn't hope so!
I can definitely see how this would impact video though.
