Anon just buy a galaxy note.
I a different anon, i have the galaxy note 2104 but the 10.1 versión, I really researched before making my purchase, some people said Ipad is better, but i investigate and it's not, maybe have a "better user interface", but when it comes to drawing, the only way you can do it in a Ipad is buy a external pen, and that sucks, basically pencils are adapted to operate on the Ipad, In change, the pen of the galaxy was integrated in the tablet, they have a special layer before the screen for the pen, and obviously was made by Wacom. Some people said that you draw with "lag", but is totally bullshit. They have the SketchBook included, but there are very good third-party programs out there, i like one called "ArtFlow" is really good and you can blend colors in the free version (i don't know if you can blend in the pro version of sketchbook. I use it for doing sketches.
