the resolution loss with software binning is exactly the same as with hardware binning - 1/2 the linear resolution when you use 2x2 binning. The free lunch of software binning is that you get more dynamic range.

minor point Greg, but perfect binning gives you 4x the signal, but only 2x the SNR if you are shot noise limited (which is usually the case).
