I love lists. I make them all the time. But new technology is really challenging me.

Do I make lists on paper, thus allowing myself the satisfaction of crossing things off?

Do I keep lists in my phone, using the memo function or the synched calendar?

Do I use one of the many apps designed to provide reminders and store lists?

Right now, I'm using all three methods and I'm not really sure which is best. What do you use? What works best for you and why?
