I too fell for this numerous times. In fact I actually went back to an Acorn RiscPC 600 for a bit once instead of a modern windows machine. It was what I considered to peak productivity for me. Built in assembler and programming language, decent quality desktop applications and no distractions.
After about 5-6 days it was back on eBay because quite frankly I realised what a pain in the ass it really was. 99% of the stuff I was actually doing was collaboration and it's really difficult doing that on vintage computing platforms. On top of that the hardware is almost always like a hand grenade with the pin out. It's going to die, but you just don't know when.
I cite this as an example for the comedy timing: https://www.youtube.com/watch?v=TU55-7dWMi0
Now emulation I can get behind because when you are completely fed up of the idea you had it's easier to dispose of it than getting rid of it on ebay :)
