Smart phones are an endless entertainment source and can also really aid in getting things done. Particularly with apps. Toting an ipad around is a little obnoxious but I do it occasionally if I know there will be some good photo opportunities. But that's really what I bring it out for. It's not for note taking, nor is it for to do lists. I prefer the good ol' fashioned notebook for these tasks. I know I'm not completely alone in preferring this method. A lot of people are in love with planners and what have you.
I write down important things, notes, dates, websites to remember and lots more. I prefer this method because I don't have to worry about losing it virtually. It will always be there unless I erase it or throw it away. I find myself going through old notebooks and enjoying what I've written and I can't get that enjoyment from an electronic.
So I have become a bit of a notebook and office supply hoarder, but I love it! I am never without a place to write something and a utensil to write with.
Do you prefer your phone for lists, planning, or notes?
