He’s saying it’s redundant to the perfect list in his head and doesn’t want to bother setting up an address book at all.
Which is fine, although it ignores the numerous benefits to setting up a contact list, such as in emergencies, for storing info beyond phone numbers, and for enabling detailed caller ID.
And syncing between devices so the list is always available.
It also ignores that he’s a tiny minority of people who prefer to memorize phone numbers, and mobile phone companies generally don’t add features that cater to tiny minorities simply because it’s not as profitable for them.
No. It used to be, with Voice dialing, you first had to store the number, and then after storing it, you’d have to make a voice recording of your own voice saying said contact. Once you’ve done all that, you can now voice dial that number for future uses. So now, in your phone you have two contact lists. Your regular one and the other list that you’ve set up voice dialing for.
The thing is, you no longer have to do that now. All you have to do now is type it in and the phone will recognize it.
