I too have had this problem....do I purchase a notebook or a book to scribble my thoughts in at the end of the day? So far...I have gone the neither route...too lazy, no time, or many other silly reasons....and wish I had done either one! The last trip I took I didn't even take a camera! Now I have an excuse to return...lol But...as you grow older, yep I'm old...52 and loosing my memory every day as it seems, I wish I had taken more notes, pics whatever to help nudge my memory of those adventures. Now....will I buy a notebook....probably not. I don't want to worry about it, getting damaged from either water or vibrations, plus what if it crashes? All lost any way. So I will rely on the good old pencil and paper I think. Oh yes...and a camera from now one.... Time catches up with you and things don't work as well as they once used to.....not that I'm a dribbling fool, but unless it is something either very good or bad...it seems I don't remember it as well as before. Write it down....you will thank yourself in the future.
