Not so much stuff I want to see "return" but I have examples of stuff I like.
I personally like late 70s, early 80s technology. I feel that before Bill Gates and he windows explosion that computer/electronics were a lot more fun(No, I'm not that old...but I've played with some gadgets from that era).
This is why I like to run emulators of old systems like Speccy portable, Atari, and DOS box on my newer Linux computers.
And...
Everything is so "software heavy" now.
The more buttons I have to press, dials I have to turn, the more wires I have to move around, and the more amber lights that light up the better.
