I think it depends on what you're looking to do with it. I don't think it is going to replace a full gaming PC for most people, for instance.

I like mine, but it is mostly the "hang out on the sofa" device while my partner is watching TV. I only bring it out of my flat on long trips, with the expectation I will use it in my hotel room. It is too big (and drains battery too fast) to be used on my regular commute. I don't really play games on commutes though.

For that use case, it is fantastic. It does make using anything like a Switch afterwards feel like a child's toy.

It also is fun to tinker with, it is basically just a PC running Linux so there are plenty of other things you can get working on it outside of Steam.
