Yeah, but it's sexy, saves desk space, and it's a good enough excuse 
for SWMBO.

More practically, I've never had an LCD lose focus on me.  I've 
scrapped four CRT's in the past decade (dual monitor setup c.1993) due 
to focus issues which cannot be fixed economically.  At least I'm not 
replacing flyback transformers anymore!  If there's a reconditioner 
who's interested in blurry monitors I've not found him yet.

So... presumably I'll be replacing the LCD's less frequently than the 
CRT's (if the bulb lasts) which will put fewer pounds of total material 
and quite a bit less lead on the landfill.  If the argument surrounds a 
single upgrade it's harder to defend, but reality is stuff fails at 
frequency f and costs rate x to fix or y to replace and that needs to 
be in the calculation.  It's probably more costly than the electricity 
the unit will use over the lifetime of the unit.

P.S.  There are some really good deals on big analog-input panels out 
there during the move to DVI.  The signal rides a good cable and is 
digitized onboard anyhow - if there is any quantization noise error in 
the display either I can't see it or it's outside the performance 
envelope of the panel itself.
