Handwriting a to do list is also way faster since you don't have to worry about app switching, typos getting corrected to the wrong word, and random occasional slowdowns that always seem to happen right when I really need my phone to work. Also it's hard to make a to do list on your phone while you're talking on the phone - yes there are headphones but then you have to untangle those, plug them in etc, even if you just need them for a minute (another ongoing issue!).
