Actually, it looks like it should be shipping soon, so it's all good.

I saw a video on Twitter where somebody ported Krux to run on an Android phone, and my jaw dropped.

Could you imagine how great it would be if there was a way to repurpose old Android phones and old iPhones to run Krux or something similar?  Obviously, at that point, the old phone would need to become a single-purpose device for security.  But, seriously, think about how many people might buy a new phone and turn their old one into a Bitcoin transaction signer like Krux if it was easy to do.  The hardware is perfect for this sort of thing.
