Your comments come across as hypocritical. You might want to change them because they are "a tad overly simplistic".
There is much more more to shooting in "normal lighting" than sensor size. Lens aperture, IS, camera processing (even RAW files are processed), AA filter, bounce or diffused flash, etc.
I would much rather shoot indoors with an E-PL1, the F/1.7 lens, IBIS, and the built-in flash (which can be tilted and used as a bounce flash), than and APS camera with an F/3.5 lens, no IS and no flash.
