I regress

Well I have decided that I am going to go back to my pen a paper to do list. I have a to do list on my Google Home page that works well if I am at school.  I got a Black Berry this summer but can not find a to do app I like (that is free).  The other problem is I can't have my phone out at school and I don't have my computer with me all the time.  My old method was I had a small note book that went everyplace with me so when I did I could check it off. Unless I can find something better I am going to go "un" tech on this (not that "un" tech is all bad).  Any ideas to help me out so I don't revert to the dark ages of paper?
