It's amazing.

It has the ease of console with (nearly) the library of PC.
I've been able to play current AAA titles, and the original Monkey Island.
It can Emulate pretty much everything the console market has as well (I mean, the stuff that a PC can emulate No Xbox One / Series X/S or PS 4/5).

And two features that don't seem as useful as they are.
It's a dedicated device for gaming
Its sleep mode works well

This means I can just pick it up, play for 10 Minutes until I get called to do something else again, pause, put it to sleep, and pick it up a week later.

Its absolutely that good. Yes sometimes you need to tinker but there are very active communities to help even install non steam games. I bought early as i was very hopeful and now i game on it more than my desktop by far. Lounging, dock to tv, on a plane im a huge fan

I use it to play pretty much whatever I want to play while I am away from the house. I use it to play Northgard in the evenings on the couch with my wife and I dock it to the TV to let the kids play Human Fall Flat, Brawlhalla, Untitled Goose Game and Golf With Your Friends.

It Lets me sit on the deck and play diablo while the kids are playing in the yard.

I am also an avid linux desktop user so I get to play all this stuff on my gaming PC when I get the chance as well.
