I use mine for scheduling and sync it up with my Time and Chaos on my home computer. With my maintream work I do a lot of site calls, so it is great for not double booking while out and about. (sure beats the tons of slips of paper I used to use..lol). It is great to have when I am at a client and they want to set something up for the next week, I don't have to "check" and call them back, I can do it right then.
Also use it for addresses, phone numbers, playing games when I am stuck somewhere, and if I need to, it also takes pictures and video.
I think it is like any tool you buy, if you make the effort to learn it well, it serves you well.
