It's like the difference between using a beautiful damascus paring knife to cut an apple, and using a Swiss Army knife to do the same thing. The Swiss Army knife will do the job, but the paring knife will feel better cutting it up. There realistically isn't anything that the electronic organizers can do that a smartphone can't, but the organizer was designed from the ground up to do exactly what it does, and nothing else. There is a joy to using something that was crafted for a specific purpose. Just like I have a bunch of calculators on my phone, I still never leave the apartment without a real calculator. And I've never reached for my phone when I've needed a calculator except for in an emergency when I was too far away from my desk.
