I've got the Jade Plus. It's nice device. I like it.

But surely your statement is BS. If someone steals my Jade Plus the only thing saving me is a 6 digit PIN code, no different to other devices. In fact, dodgy Ledger even has a 8 digit PIN so I could argue it's safer against theft.

If anyone can access my PON in my Jade, then they can freely access the blind oracle.
