I am often getting phone numbers for work, friends, and sometimes family in my inbox. What do I do with these? I know most people would say, well just put them in your cellphone. There's one problem with that: I don't have a cellphone. So how can I do this paper-based where I can have all my contacts with me at all times? Should I keep a list of them in my Hipster PDA or should I go out and buy a planner/calendar with a place for such contacts?

Your thoughts, please?

Thanks,
Dustin
