I'm tired of having to worry about carrying a phone and getting it wet, or leaving it somewhere, or dropping it. I keep looking at Apple Watch thinking I could have that and not ever worry about a phone again. Will I be frustrated if I try to use the Apple Watch with no iPhone? Also, is there such a deadbolt that can let the Apple Watch unlock it with nfc or something? I'm thinking I won't need keys, wallet, or phone if I had Apple Watch. Am I wrong? Will I love it?
