I get most of my ideas anytime , it might be a time that happened in the past with friends and friends friends. or it could be a present time hanging out on the weekend sitting at a bar , or resturant, or on the hour drive to my friends house. Pretty much anywhere, I have not traveled outside the US , but Even at my young age of 28 I still have traveled a whole lot and done alot of things and I have a deverse group of friends and family.
I too have to quickly write things down and i have them scattered all over the place untill I got my Pocket PC , which i don't know what i would do with out it.
IF you don't have one I suggest getting one cause this item is like 100 thing in one. It's a digtal voice recorder, contact book, Master remote control, mp3 player, GPS, oh yeah it plays movies too, a dictionary, oh yeah becasue it's windows based it does everything your PC at home does, like Mircosoft word, excel,etc.. adobe , plus games , etc,etc.....the list goes on , , so I keep al my ideas on there and i can transfer to my desktop later .
