Last time I upgraded my phone, I looked at getting a Samsung Note: I’ve wanted pen input on a phone for so long. Then I considered the extra weight and bulk, and the poor condition of the second hand one I was looking at, and decided I can just just use pen and paper.
I like to be able to scribble things on paper, though my handwriting is terrible. For anything to last long for me, I want it digital, but random thoughts, calculations and stuff, I like paper and pen.
