To me there is nothing like the book on my dashboard. Mine is 5 x 8 and I have a monthly calander, several "notes" pages and the telephone directory in the back. I can go backward, foward, make calls and schedule an appointment with the book right at my fingertips. I designed the whole thing in my excel program. At first I created this time card set up on my computer. But I still keep coming back to the book. It's just easier.
