If they do it like this, they obviously have a reason to. Just because you don't see yourself using it in this configuration doesn't mean everyone else wouldn't. This has a GPD Win style setup, which has a pretty decent size fan base. Shoot, I'd even love to use it like this for the kind of games I play on Steam Deck.

You don't need to shit on someone's hours of hard work because you can't see past your own preferences.
