Livescribe great for telephone
If you put one of the earbuds connected to the pen and hold the phone against that ear, as you would normally when using the phone, it will record telephone conversations.
I find this extrememly helpful when speaking to insurance companies for instance who are ratteling off information that I think I understand and realize I didn't after I hang up the phone.
Organizing those N/A etc into your system?
You mentioned identifying Next Actions etc in your notes. what is your "set-up" for incorporating those into your GTD system? ...getting them from Livescribe notebook to whatever else you use for list tracking? Or does your system live in Livescribe?
