We'll talk about how useful that is when you're in a non-ideal lighting condition trying to find a phone number and typing it in on the front.

I used to remember pretty much all the phone numbers of all my relatives and people I'm in contact with, even the international ones but with the coming of cell phones something else has happened: people switch phone numbers far more frequently today than they did in the past and the ability to re-program the phone but keep the mnemonic the same is actually far more useful than a piece of paper.
