Hmm, having already previously owned the Note 2, 3, and 4 phones, I have mixed feelings about this rumor. On the one hand, it's rather cool to scribble stuff sometimes. But I noticed that as time goes by, pulling out the stylus becomes less so, at least for me. It was so cool to write on the screen the first time with my now ancient Note 2 phone, if nothing more than to show off to my iPhoney friends. But that was then, now is now.
I recently bought a new Lenovo L380 Yoga Thinkpad laptop with a touchscreen and stylus pen for writing. Yeah, I dabbled with the cool stylus pen that is garaged inside the laptop. Even installed and played with a few different "Paint" apps. But after a few days, the stylus pen is now getting lonely inside its housing port. I do tons of screenshots on my phone, but not much writing with the pen.
