I was using the Galaxy Note 10" 2013 model for a year as a substitute of real paper and notebooks at work and at home.
It was too small to substitute the A4 size (~us letter)
Me, a friend, and his friend recently bought a 12.2" Galaxy Note Pro which is almost A4 size and it's just awesome. Those two friends don't use their iPad anymore:
* True pressure sensitivity and pixel perfect accuracy
* Good size and light weight to substitute a real paper notebook
Those are the only two things needed to substitute paper: Decent size and decent stylus. Those wannabe iPad styluses are just trash compared to a good Wacom Stylus for the Note series.
You will know it if you have used both: Crappy iPad Styluses and real Wacom Styluses on a Note Pro.
In what way?
