The Steam Deck is HUGE. I thought my Nintendo Switch was big until I got it, but it appears so tiny now in comparison.
I generally keep my Steam Deck at home and play from the couch. It’s awesome to be able to pick it up, play a game for 15 minutes, hit the power button to suspend. Come back later and pickup where I left off. The Switch does this as well but the Steam Deck supports games more my genre and style so it gets more use.
