Personal digital assistant or paper for on-the-go collecting

Now that making phone calls is only the 5th most popular thing that people do with a smartphone, perhaps more people are using their smartphones as GTD digital collection devices. But even though most people always carry their phone, some of the most savvy GTDers also use pen and paper for collection. The key is to know what methods reduce the friction in your system. If the device is not easy to use for getting stuff off your mind and into your trusted GTD system, you’ll tend to use it less.

How do you get things off your mind when you are mobile? Digital, paper, or a combination?
