While Doctors and HR people might not care or understand about the hardware in their devices, the IT people who actually purchase and manage them do. For POS/retail use, small businesses who don't have IT support might not appreciate it, but larger retailers probably would. Now that Google is insisting on being in control of all modules, the number of modules that will be available is going to be far fewer than it would have been with an open standard. Companies that make specialized hardware for particular industries won't bother making modules because of having to sell them through Google's marketplace. Google's apparent movement into hardware and software DRM sounds like it will make proprietary modules not meant for the general public much harder to do, if it's even still viable at all.
