I really noticed the latency problems when it came to faster games. Anything multiplayer and you're definitely getting a disadvantage. Especially on the FPS side of things. But for single player stuff, it felt rather responsive for the most part. Even in Fallout where once you're in those battles and there are a few people running around, it didn't feel like there was a big difference between the inputs I made and the actions.
I do think the tech behind it is impressive, it's something that is cool to see, just it solves no problems for anyone really. You are just better getting your own desktop or paying the upfront cost of a handled like a Steam Deck or Switch. Especially given their lower prices between $300 and $600.
The main problem isn't even a technical one for me, the thing I hate is the idea of game rotation. Imagine getting into a game like Fallout and then the cloud service tells you they're removing it in a week or two.
I think this tech also shows that the people that create it and push it don't really understand the mentality of the consumer. The consumer wants ownership, and the best quality they can get. And they are in fact willing to pay for that.
