Sadly you missed the golden era for the Mac. Back in the PowerPC days there were lots of developers making fun and useful tweaks and there was a fair amount of configurability built in. It really was a professional's Unix OS back then. Over the past decade or so I've watched the possibilities narrow with every passing version.
Although I think throwaway is correct that that isn't what they meant, people do indeed lease land in the United States.

Easy. I'm already envisioning all the ways this device could make my life easier. I would no longer have to juggle RFID keys to multiple clients' premises. I can lock and unlock my 1994 BMW that uses a long obsolete RF keyless entry system that is difficult to obtain replacement keys for. I can adjust my RF controlled lighting system at home without having to dig for the remote. So much of the world runs on RF that having a device that can speak to everything is invaluable.
