First thank you for your answers.
then some more questions
I can take notes at any zoom level?
What happens when you zoom in or out on a page with notes?
Battery life is my real fear, 8-10 hours of working time means mainly that i will have to recharge it at least 3-4 times a week. So the number of recharge cicles of the battery will be an isse like on my laptop.
I just hope it uses a good quality battery
Thank you
