LCDs are physically incapable of producing black, its a limitation of LCDs in general, this causes the darker colors to run together, play Doom 3 and you'll see what I mean. Flickering in CRTs is for the average person unnoticable over 80hz, radiation is a non issue the US National Research Council determined after a 3 year study CRTs do not pose a threat to human health. Geometry can imperfect on both CRTs and LCDs, the curve if the tube doesn't produce any noticable distortion. To get a quality 19" LCD (NEC Multisync) costs $450, while a 21" CRT (Samsung) costs $450, the CRT has more screen area, and can do higher resolutions. You didn't address the horrible color reprodution on most cheap LCDs. As endgame said earlier to each his own I prefer CRTs, and alot of people prefer LCDs its a matter of preference.
