I was actually drawing on my Note 3 before this. My issue with it is that the colors don't match my monitors for my PC or either of my laptops AT ALL. I tried changing the color display on my Note but it was impossible to get it anywhere close to a computer screen, so I ended up getting a picture that was really bright and vibrant on my phone but on my PC looked like it had almost not color at all. Also I love the screen being pressure sensitive. The screen size didn't bother me, though. I still plan on using my Note 3 for if I'm out or laying in bed, but probably only for sketches and I'll do all my inking coloring on my tablet.
ALL THAT BEING SAID, if you can just be happy with your Note phone, more power to you. It's nice to have everything in one spot and you'll save some $$$
