Close but I'd say it's more like a handheld console with a Chromebook attached.

Steam Deck apps (mostly) have to come from a Flatpak repo to install correctly but Flathub (the default repo and therefore defacto app store on the Steam Deck) has lots of the common apps for daily use, even if they are largely unofficial/unsupported versions. So for 95% of people, it's definitely usable as a laptop/desktop replacement, but if you want to develop or want stuff outside the Flatpak repos, it's a bit of a hassle.

That said, I love this thing.
