So why does it matter? On Switch, I had to expensively rebuy games at high prices, which then ran poorly and didn't support any kind of settings to try to fix the situation. On the Deck I get all my desktop Steam library and I can change game settings until they run as I like (within reason). I don't see how those two are comparable purchases - I either get a console which runs poorly and demands 40$ for games that are like 5$ on Steam... or a console that already supports my existing library AND on top of that allows me to stream games from main PC at full detail and framerate.
