I totally would not be on this path of physical improvement via doctor without my Droid. Appointments go into the magic phone (my google calendar) and today's schedule is the first thing I see every time I look at my phone. No appointment cards to lose, it doesn't mater if I forget, because when I wake up (the dammed thing is also my alarm clock) it shows me that I have a whatever appointment (physical therapy, podatrist, osteopath...) andwhen and where.
I can screw many, many things up, but my dorid does all my organization for me. (It also means that if it isn't in the magic phone, I'm not doing it.)
