Artist here, just wanna share my 2 cents.
If you are doing art as a hobby for fun, the ipad pro 11/13 inch is great. Coupled with Procreate, which is the best painting software on Ipad (till Photoshop arrives), you are good to go.
But if you want to dive deeper, do some real cool work, maybe even go professional, the Ipad is really NOT recommended. Since it is actually more troublesome to do art on a touch device without a keyboard, and Ipad's file management system is just plain retarded.
So I'd actually recommend getting an actual laptop, most importantly, focus on having a dedicated graphics card, NOT integrated ones, and having sufficient RAM. The ram for the graphic card is ideally 2gb, and your laptop RAM is ideally 8gb and above, these specs will give you quite a smooth performance. Don't worry about CPU speed, most laptop nowadays have more than enough.
Then get a tablet. Huion for cheaper range, and Wacom as industry standard. I don't have a Huion so i can't attest for the quality, tried it once at a shop, seem decent enough.
What I have is Wacom Intuos 3, a very old model, but imho, it is an excellent investment since it functions perfectly till now, even though I have dropped it twice. And if you don't draw very hard, the pen nib can last for very long, for I have not once changed my nib.
I have both the Ipad pro and laptop, so I think my assessment is pretty accurate. If you have any questions, you can ask me of course.
