Expensive is relative, and compared to other consoles the Steam Deck is competitively priced. Despite the high level of hackability it's not "just a tinkerer' device". It has a purpose that it accomplishes quite well. Outside of installing Dolphin and Yuzu I haven't done anything with it outside of Big Picture mode. Haven't really felt the need to more, but it's nice to know I could.

Why some people are so hell-bent on seeing the Deck fail is a mystery to me. Either they are simping for some company in competition with Valve/Deck, or they are bitter about people having fun. I could understand the criticisms of it, of which there were many upon initial release, but overall it's a pretty good experience these days.
