Yeah for small diagonals almost nothing I said matters but with big screens sizes like 46" and more, which HD CRTs never had, such stuff matters.
One problem is that the nicer contrast and black levels were a real good argument years ago when LCD and Plasma tech was in it's infancy. Nowadays LED-LCDs (colors) and new Panny plasmas (black levels) blow CRTs away.
Can't wait for OLED to become consumer ready for big sizes. Then we will be really blown away.
