Just like most developments in the bitcoin world, I'm having a lot of trouble figuring out what this thing actually does and why I want it. Isn't the whole major selling point of Bitcoin that it isn't physical and is instead totally digital? What does a "bitcoin command line" even mean? "With this pocket-sized device, if you are an entrepreneur or developer, you can now instantly buy or sell digital goods and services at the command line using Bitcoin." Isn't that already all possible with just bitcoin itself? Why would I buy this thing?
