In my case, I would keep using my old consoles and computers, there's a nostalgia factor that can't be removed in my case.
It's all about the search, look for the game/s, look for the system, hook it up, turn it on, put the cart or disc in, listen that sound or music, close your eyes and for just a couple of seconds you are back to that time when you played it for the first time.
On the other hand, other people don't like physical media and it's a way for them to play those games. That's market segmentation.
