I, too, can't handle 30FPS on many games. Fortunately, there are still lots of recent games that can hit ~45FPS, which--while not great-- makes it much more bearable. And if it's too poor of performance, I will often just stream from my desktop while in bed or on the couch. But again, I primarily use it for less demanding games to begin with (e.g. I've been playing a lot of Dragon Quest X on it recently).

I'm not saying it's worth it for everyone, but if the choice is between its closest competitors and the Deck, I think the Deck offers more value for the money spent.
