Correct, Nitrokey Storage includes an encrypted mass storage (which
Yubikey doesn't). Furthermore Nitrokey is open source and open hardware,
allowing independent security reviews (we passed one audit already).

Only Nitrokey U2F, which is a separate product, supports U2F. The others
don't yet. However we are working to integrate U2F into the other
products as well.

It's a completely separate smart card placed into a Micro-SIM socket.
You can't miss the SIM socket in the layout and BOM. The smart card
(OpenPGP Card) itself may not be in the BOM because it isn't sourced
through the ordinary electronic distributors but from the vendor directly.
