I love that you can change the background to solid black (single color), line a page for tasks, or show a weekly schedule, or show chart points. Very helpful. At first I couldn't get this thing to erase marks made by impact or whatever. Accidental marking. But then I read the little "booklet" that came with it, and thank god I did because I might have thrown it out if I hadn't read that sometimes you have to reset the battery by using the Press "Delete" key 10 times in a row. This may be necessary if the battery has not been used for a long time. I've never heard of this problem, but it definitely worked!
