I think they had to add a screen in order to compete with Trezor and KeepKey both at $99 now. Smart move. If I read the specs right they have fixed the problems people complained about: you can now initialize a Nano S on an infected computer and no more security card to bother with. I do note they only allow for a four digit PIN though. I would feel more comfortable with a longer PIN. And they beat both Trezor and KeepKey to be the first to offer a hardware wallet for Ether looks like and at a cheaper price. I look forward to buying one.
