[Doctor Mac]

I find that I need to mentally separate out what I could be doing on the iPhone into "email" "phone" etc categories. In some ways this is cheating on contexts, but not really. If I'm on the train riding home I can do some email on the iPhone, but not really make phone calls. Whereas if I'm driving home from the train station I can make a call but not work on email. Same device, same tools at my disposal, but in reality different contexts.
