Do I have to buy a special notebook in order to use the Smart Pen and the Notes App? I have several notebooks. How can I define the one I'm writing on? What should I do if my Smart Pen doesn't turn on? Do I have to turn my Smart Pen on/off, or is it automatic? How long does the Smart Pen battery last? На какие случаи распространяется действие стандартной гарантии Moleskine? Сколько она действует?
