It's not a matter of performance. My SD can virtually all AAA games on Steam with reasonable frame rates. It's a matter of ergonomics, physical comfort, mood, and minset when I'm with the Deck vs with my gaming PC or gaming laptop. On my battlestation with a 32" 1440p 144hz monitor, it's "overkill" to run many of the indie games I want to play, not to mention not nearly as comfortable if I were to sit in front of my gaming chair instead of laying in bed or on my couch. Also, when on my computer, I'm always on Discord and I run a Discord server with 100+ people in it from all around the world. This incenticizes me to play multiplayer games with them and further demotivates me to launch a single-player or indie game.

On the SD, it creates an environment where I naturally seek to launch single-player, indie, story-focused, and relatively casual games that I can almost isolate myself and unwind with a good story in the palms of my hands. The SD allows me to extend my gaming to several parts of the house and world I've never played PC games in before. I've tried gaming laptops in bed via many methods and they are not comfortable. This is where SD really found its niche IMO.
