The real drive is we don't want newbies who don't know any better to be ripped off by buying a glorified brain wallet and end up losing all their hard earned bitcoin.

The only reason the bounty wasn't awarded is because Bitfi kept changing the goal posts and then cancelling it all together so they didn't have to pay out. The conditions were met several times by different people. They managed to extract the seed in plain text from the device, meaning all coins can be instantly stolen. Bitfi's claim was their wallet was "unhackable". I'm pretty sure extracting the seed counts as being hacked.

Even forgetting how horribly insecure their device is, even forgetting it had been hacked wide open multiple times, even forgetting the seed is extractable, even forgetting you can gain root access and install custom firmware; even forgetting all that, at the end of the day, it's still a brain wallet. Brain wallets are even worse than web wallets on the scale of "good security".

Buy one if you want, but realise that your funds are at constant risk of being stolen, and there is literally nothing it does that cannot be achieved more securely and for free with some freely available and open source software.
