Just got a 12.9 ipad pro and pencil yesterday and loving it. I am really afraid to constantly tap and draw with the pencil, sometimes rest my arm/wrist on the screen to write, maybe while doing so my metal watch band will scratch the screen. all kinds of reasons to be afraid of scratching this beauty. i have a tempered glass screen protector coming today and will test, but i know it will always be sharper and more vibrant without one. Any of yall use 12.9 ipad pro without a screen protector and use the pencil daily?
