It’s complicated, especially as laptops have gotten thinner and tolerances tighter. Dell and Lenovo/IBM used to have laptops with drains.
Lenovo definitely has splash resistant laptops, and most semi-rugged devices are spill-safe, but spilling coffee is still a service event as the cream ruins the keyboard.
Doesnt hardware getting smaller and with tighter tolerances mean they it's easier to waterproof something? Less surface area to protect and tighter joints means there's less gaps to fill.
