I agree with you. Steamdeck is amazing but people are often over-enthusiastic about what a handheld device can do.
The most comfortable and consistent gaming experience is still a regular stationary PC. But if you really want to play Civ5 on a train then sure the Steamdeck is there for you. I just never felt the need to game something that bad.
I just don't want to sit at my desk after a whole day of work, and I've got an RTX5090 PC for some stupid reason. I'd much rather play games on the sofa on my steam deck sitting next to my wife or play in bed.
