I use a nice 19" TFT at work, and it's a beauty. At home, the 6 year old CRT is on its last legs, and when it goes it'll definitely be replaced by a TFT (LG L1715S 17" TFT 16ms £150).
It's so much nicer looking at a TFT than a CRT. Especially when you're concentrating, ie writing code and staring gormlessly for inspiration
