It's fairly easy (not always cheap) to get almost any old computer you could think of in very good condition to run the programs you like without further hassles. This can make a lot of sense because sometimes there are hassles associated to virtualisation/emulation/modern hardware.

Maybe you feel at home using WordStar 4.0 + VGA text mode in a CRT monitor. If that's the case, you can't beat the ease and responsiveness of a DOS computer. I have this conviction that there's nothing wrong with that.
