Yeah, this person is so deluded in their steam deck zealotry that they've lost touch with reality. In one comment they argue the steam deck's value is in its Linux OS and ability to emulate Switch games, then in the next they argue that the thing is "much more convenient and no fuss". The only convenience is in the portability. If you aren't interested in sacrificing power for portability, that offers zero value. As for emulation, arguing that is no fuss would be laughable. Even native steam games can be iffy, requiring troubleshooting like swapping proton versions and entering launch commands. There's a reason ProtonDB exists, and the Xbox doesn't need something comparable.
The Steam Deck is great for what it is, but the only console it compares (and is vastly superior) to is the Switch.
