Speed: While digital may be faster than pen and paper when it comes to searching for phrases, sending copies and the editing of final drafts, paper still takes the cake when it comes to certain tasks. Referencing shopping lists, story notes and master task lists is far faster when I only have to flip open a notebook as opposed to firing up a device, logging into it, finding the app, launching it and finally locating the particular list I am looking for. It's also extremely convenient to jot down thoughts from a brainstorming session on paper when battery power and internet access aren't available.
The one area where things can get a bit tricky is the scheduling calendar. Being able to jot down an appointment on paper might be markedly more convenient than keying it in on your phone with two thumbs, but you will still need to migrate the information to your digital version at some point, particularly if you share an online calendar with others. Personally, I made my peace with this when I realized writing things down by hand first helps me remember them more easily. Also, by using the paper option for other types of notes, I avoid the digital distractions of incoming messages, technical snafus and social media updates.
