I have a mate with a 24 in TFT, 22in CRT & 19in TFT on 3 machines, his Gaming / 3d Studio Max PC (he's a full time 3D modeler by trade) uses the 22in Mitsubishi CRT as its by far the sharper of the three, supports many resolutions and had no dead pixels! He got it from a large auction site ages ago.... - under £50 inc postage(!)

his other two machines are used for browsing / mail / docs etc on his lesser #2 & #3 machines.
I'm still a Caveman & also still have CRT , a 21in which is great. I blagged it

from another mate of mine who's recently got himself a nice looking new 24in TFT to compliment his 8800GT graphics card , Battlefield 2 now looks awful for him ! - he cannot get his new monitor to run the game @ his monitors native / optimum screen size which is a common issue so I believe resulting in a faint but very noticeable blurring issue in that & a few other games. (Many fixes tried, with no success I may add...)
The sheer size of the CRT is an issue certainly.
My PC's set up on a large kitchen table!

the CRT balanced over the edge, it still takes up half my available "desktop" width......

not too much of a problem for me thankfully,I have a a large table in a large room....
Imo, for the quality & size of screen I get in return, especially viewing web pages, then the CRT still wins in my book. If & when however, my 21in dies or develops issues, I'll be off to upgrade to a TFT widescreen straight away, bowing to modernization I suppose.

It is the future, thats beyond doubt, and games like COD 4, Crysis etc are obviously developed with such new screens in mind I'd have thought.
Until it breaks or,the reverse of the BF2 problem arises - a game supporting widescreen only for example, "If it ain't broke, why fix it?" remains my view.
If I were you, I'd save the cash & in 12 months you'll be able to get better, larger screens for a similar cost. Then, by all means, I'd say yes its time to ditch the CRT.
Happy Christmas mate.
