I just don't like the 'glowing phosphor' look we've all sort of gotten used to. As for the artifacts you saw, the DMD can switch thousands of times / second - you had to be seeing a digital artifact from something upstream.

Any of the 'shine light through colored glass' systems seem to have an advantage in that the 'colored glass' can be a wide range (and probably more optimal) color.

I don't like 24fps either - it's always bothered me, but the color gamut in 'film' is generally pretty pleasant.
