I LOVE day-planners and am always looking for the perfect one. My current one is a red Moleskine which is just about as perfect as they come.
(I heart Molies) Of course, I had to decorate the cover since the original was quite plain -- if red can ever be considered plain! Youngest Daughter gave it to me, and annotated it as well, so it is especially nice.
But I just ran across a new type: a Chronotebook. How clever is this! You have a clock face in the center and LOTS of room to write. Hmmm....
I just might need to switch from my dear Moleskine next year.
