It's cool but I don't know why I need this. Why is it better than using a regular hardware wallet?

Likely oriented mostly towards pre-coiners. Why to buy another device for Bitcoin when you already have YubiKey?

Better UX. If you've ever used a yubikey, it's easier to use than a hardware wallet.

except you can recover a hardware wallet
you can't recover a yubikey

Typically, you configure two yubikeys and keep them in separate locations.

There are big tradeoffs being made here, so I wouldn't diminish those, but you can back up the private key stored on Yubikey.
The Yubikey isn't a signing device. It's a storage device.

maybe you can recover from a backup file
but you can't deterministically rebuild from a seed phrase
yubikey can also be used to sign ssh, fido2, webauthn, pgp etc
edit - I see it is indeed a storage (not signing) device in this context

  1. costs $25, less than most HWWs
  2. can use for other 2FA and MFA
  3. not obvious for bitcoin, so won’t be on a “list” of ppl who buy bitcoin only products
