I already spend 8 to 12 hours a day in that "keyboard and mouse" position for work... I ended up never playing any PC games (other than a few Civ games here and there) because of that.

The Steam Deck is great because you can play anywhere. On the couch, a net, in bed.

And the Switch is only comparable to the Deck in form factors. The Deck has way more gaming options and freedom. I bough one in place of the Switch, but I can imagine that if like just the Switch games, it doesn't really make sense to have both.
