2do lists

I read about an easy to use "to do" list system that I'm trying out.

You take pictures with your cellular phone camera to remind you of the things that you need to get done.  Then I just look at my saved pictures to see if I've left any picture notes for myself.

For instance:

I have to remember to have a laptop at Alpha tonight.

I also will need a thumbdrive to record the talk.

I need to remember to sober up Chris before his talk.
