The biggest pro of two opposing ports: you could always charge your device regardless of orientation. With just a port on the bottom charging while scrolling in the bed is often uncomfortable
This is my biggest problem with my switch! I have to awkwardly hold it when I’m trying to ay laying on the couch or in bed. I hear the Steam Deck has a port on top for charging so it’s already begun!
Lol my set up is a 22" 1080p on the left for basic web viewing, 28" 1440p center for games, and a 32" 1080p on the right for videos/twitch while I’m playing games
