I'm not going retro but I am trying to downsize. I used to have 3 monitors and 2 desktops in my office. I now have 1 monitor and 1 desktop. My end goal is to get comfortable with doing everything on a single Macbook. I really want to be rid of all the distracting crap. I feel like 3 monitors made me lazy and undisciplined.
Imagine being able to close your laptop, get in the car and not have to think for one second about whether or not you brought the appropriate accessories for productivity. This is about where I am at now. The big, multi-monitor battle stations are a prison.
The technology should serve the human. Not the other way around. Constructing a small datacenter in your own home is probably a good example of the later case.
