Can't leave without doing lists ? Want to have lists on your iphone, Ipod, blackberry, organize our to do list. Go check Remember the milk.
I am testing it for the moment, and I am not fully convinced yet. Oulook ? Remember the milk ? Paper ? Testing several options. Haven't find the best one for the moment, depending on my needs (perso to do, pro to do, others ...)
I like the post it option and paper one, but it has limits. Hope to find the right solution soon.
