Phones/Tablets?

Does anyone else here use their Phone or Tablet to do graphics? When I say Tablet, I mean a tablet computer, not a tablet specifically for drawing obviously. I just recently got a stylus and the Sketchbook Pro app, and ended up doing a little drawing. I never draw to be honest besides doodles on school papers, but my Nexus 5 was a great experience. I wouldn't mind using the Nexus 7 for the bigger screen, but it honestly seems like a great alternative if you want to draw/paint on the go, or you want a tablet interface like I did. Here's a quick little example of something I threw up in 10 minutes. I realize how bad the coloring/shading is, I've always been pretty bad at it but hey, now I can draw whenever and it's a lot easier to fix mistakes and change things.

I do not use anything besides my laptop.

I would suppose using a stylus would help. Since PC styli are pointy.

Edit: not sure if "styli" is correct. Fuck it.

Never used anything other than a PC, more comfortable for me, I do use a drawing tablet, but have never designed on anything other than paper. I suppose a sketch on a phone would work as well.

What I mean by designing on paper, I sketch out most of my work before I do it. Logos, Illustrations, etc.
