I find that often, having a tool that enhances something you never did doesn’t make you start doing that thing.

But there are exceptions. I never had an address book or calendar until I had a Palm Pilot. It might have just been that I was becoming an adult at the time, but part of it was probably a barrier to use factor. The Palm was a small thing I could carry to class, keep near my phone, bring to my internship job, etc. It and the need for organizing did conspire to make it my first real organizer and my first time having that information organized at all.
