Yeah. You're basically buying a laptop crammed into a small box. May as well get a laptop if you need the small footprint and portability or a desktop if you need the price-to-performance.

Also, the Steam Deck thing people keep repeating is terrible advice. Even these can power their components somewhat robustly. A docked Steam Deck is still a 10W APU for no good reason. It depends on use case, in that you also get a handheld out of the deal, but if you're looking for a primary device even a laptop would be a better choice.
