I have a couple of 21" FD Trinitron G1-based CRT monitors and would be hard-pressed to give them up for any LCD. 1600x1200 at 95 Hz with lower resolutions up to 160 Hz and no resolution rescaling artifacts, hell yes!
However, if I luck out with this one deal I just found, one of them is about to get replaced with the Holy Grail of computer monitors: the Sony GDM-FW900. 24" of widescreen CRT goodness that can handle 1920x1200 at around 95-100 Hz, from what I've read. If I can get it, I won't ever need another monitor for as long as it works!
LCDs are always full of trade-offs. Non-native resolution scaling, refresh rates, input lag, response time, viewing angles, general image quality, and so forth. For my uses (predominantly gaming), the top-of-the-line aperture grille CRTs do not compromise where it matters most to me, and I don't mind the sheer weight and bulk once I get them in place.
It's too bad that SED/FED never really took off, plasma is subject to image retention and doesn't come in PC monitor form, laser DLP is hideously expensive, and QLED displays are still several years off. Those technologies might actually have a shot at displacing CRTs for being the best gaming displays. LCDs certainly won't; good as the IPS and AFFS+ panels may be, they're still fundamentally flawed by filtering the image itself out of a backlight.
I'll admit that I get tempted sometimes with higher resolutions more in line with today's widescreen standards, but the typical 1920x1200 IPS LCD costs more than what I can get the FW900 for and still has the tradeoffs I mentioned earlier.
