Android for example is good enough, but far from Great IMO. Granted, this is all subjective but an overhead sprinkler whose sensor is a part that melts/deforms with heat is timeless solution that just works (1879 https://www.google.com/patents/US218564) . An electronic sensor could work, but has far more failure modes. Now compare this with say Facebook whose design regularly undergoes significant revision. |
