I went to a ramen place in Tokyo and to order ramen you had to insert money and place your order via this machine. This felt like going back to the early 90s but in a way that we are definitely not used to in western countries. It had a very retro futuristic vibe!
There's something satisfying about flipping or sliding a phone. I have a Z Fold 3, and I love it, but sometimes I miss my Razr, or my sliding dumb phone with a qwerty keyboard.
