instantly flashes a much cooler text-based operating system

turned this ipod into a cold wallet (it can stil play music)
so if i'm ever out and someone wants to send me money they can scan the QR code, no need for a phone

Neat!! 

Can i plug it to my computer and use it to sign wallet transactions?

It’s really just a QR code that resolves to an address. Functionally no different than printing a QR on paper. Still cool 😎
