I don't mean BETTER. That's a different conversation. I mean cooler.

An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.

If a CRT goes bad it can actually make people sick.

That's just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.

Okay, maybe my town is just not up to date, but these are still in use at all the banks and pharmacies where I live. Are they phased elsewhere?

I haven't seen one in years, but the fact that they're all used is awesome.

The Kroger pharmacy here replaced their awesome pneumatic tube with a boring sliding drawer.

They are used in some hospitals in central Europe

In the Netherlands I see them in nearly every big hospital. I think for sending blood samples to the lab quickly. (Possibly among other things)
