what stylus are you using? thanks for the screenshots!
I have gone through three different styluses ... each switch being a vast improvement from the previous.
I currently use a mesh tipped stylus from Boxwave (right in image below) - as opposed to a rubber tipped stylus (left).
A mesh tipped stylus glides accross the screen with effortless resistance. If you get a rubber tip - and especially if your screen is clean, then it will grip the screen - you'll find yourself trying to push the tip across the glass display with much resistance. A mesh type is a VAST improvement ... it glides across the screen very easy. It flexes a bit. Don't worry - it will not scratch your screen at all.
I feel that I could take notes all day long just as good as with a pen and paper - no more fatigue.
From Amazon, the Boxwave that I have cost around $12.00 ( going from memory there ). There are many styles.
Good Luck with your decision, let me know what you decide.
