The identity layer of nostr makes all the difference. Many wallets don't support address books so you would be entering the recipient every time.
That is great, but if I understand right they could have done this with any other custodial wallet like nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq or nostr:npub13ljnkd633c7maxatymv3y2fqq8vt3qk7j3tt0vytv90eztwgha9qmfcfhw, right?

Hmm, some don’t. But botg WoS and Blink do. Don’t get me wrong. I love Nostr, I am just not sure this is a particularly unique use case.
Other apps might use your phone book entries but nostr is cryptographically secure. I bet that nostr will gain most of its growth from this social graph being leveraged by all kinds of apps.
