I still have a high-res Phillips 15" CRT to hook up to my servers for console work - but it stays disconnected most of the year. The workstations both have wide-screen LCDs with high refresh rates and we have been really happy with them.

Sometimes it is fun to go back and play an arcade game on the old CRT just for the authentic feel, the phosphorous persistence and the "plink" sound when you shoo away an annoying insect from the glow of the screen with the flick of a finger ;)

If you are happy with your CRT and it is still working fine, hang on to it.

But, Yes. You may be the last of an era.
