I did a project a while back with devices like these. Super rugged shell, giant battery and, in this case, a powerful IR barcode scanner. We built custom apps for warehouse workers and shut access to anything remotely fun. No mobile data or calling allowed, no internet except one hardwired wifi network that talks to shipping systems. Having an old OS is fine because they don't need to be compatible with much and security isn't a big deal because they're so locked down.
