I personally don't see much point with it. A RPi4, with 4GB, a dedicated case, and an additional keyboard (many of us have one spare laying around anyway...) that will be much better than the one in the RPi400, and you're all set. For cheaper. Even with the RPi4 8GB, this will be cheaper or same price, especially if you already have the keyboard. I know some will find it handy to have it all in one package, but as others have noted, construction is really meh IMHO, so this isn't really worth it. But, if it pleases some, hey, why not!
