There was a DEC VT320 in my attic for years until Mrs Pcolbeck made me dispose of it a couple of years ago :~(
When I was a PSO, we had a Wyse VT-120 clone liberated from the Physics department skip, that lived on top of the fridge, logged into a Linux box in another room, running BitchX. This enabled us to have put-the-kettle-on / does-anyone-have-some-cash-for-the-meter / come-here-and-remove-your-festering-pile-of-ming-from-the-sink-you-boabword conversations up and down the stairs at sensible student times like 2am, and with appropriate use of all caps and multiple exclamation marks, without waking our gratuated housemate who had a job that required audax o'clock starts (because BloodyTrains).
When barakta came along, this Just Worked for her, and so it came with us when we moved out, and was still in service until about 4 years ago, when it was replaced by a Raspberry Pi and 10 quid from eBay monitor.
The great thing about a serial terminal was that you could turn it on from cold and hit <ctrl><L> and be at a working IRC window complete with scrollback in about 5 seconds. The Pi does somewhat better, by powering up the monitor as you walk into the room, but at a cost of a couple of watts quiescent power.
I imagine we were one of the last users of the things for some pratical application that was neither retrocomputing, art, nor control of some vastly expensive piece of industrial/scientific/banking equipment from 1983.
