In an interview to Linux Voice, not long ago, Eben Upton said:
"You can build a business around [Raspberry Pi] because you can depend on them existing [...]"
Hence, my question: Has the Raspberry Pi already been used to build a proprietary product?
Say, for example, a console running a piece of closed-source proprietary software in kiosk mode or anything else?
P.S.: Apart from Eben Upton's own Raspberry Pi Trading business...
