I wish someone would make a mounting case with clamps for sticking a mechanical keyboard and trackpad of the user’s choice together, laptop-style.

Maybe also have mounting points for screws like a VESA-style mount does, so that trackpad and keyboard vendors that explicitly want to support it can have a less-ad-hoc mount.

The laptop form keyboard/trackpad form factor can be really convenient, but the handful of all-in-one devices out there are kind of limiting.
