This is a serious planner system and when they say system they mean system. It even comes with online training. For those of you who espouse David Allen's Getting Things Done principles (I think he got his start at this co.) this system utilizes a next actions list that folds over each day so that you don't have to rewrite your list. Very efficient indeed. It's also got forms for meetings and notes and a unique system for handling frequent contacts. Plus it's actually part of the permanent collection at the Cooper Hewitt. I don't know of another planner that can say that.

I used my system in my Filofax binder as the binder that came with the system was hideous. Oh, and this system is pricey as an initial investment but they claim you could regain 1-2 hours a day so I guess it's a small price to pay.
