I'd like to start painting, while I like the effects of watercolor the best they seem like a hard and expensive medium to waste supplies on.
Would It be a better Idea to learn to paint digitally (I have a, note 2, and an intuos 3, and I might buy a note 10.1). Then learn acrylics and watercolor?
On that Note, has anyone painted on a Galaxy note 10.1? How is it?
Can you draw on paper or not?
Dosn't matter if you want to paint digitally or analogically you need to know how to draw.
Watercolor maybe cheap but is also one of the hardest mediums to master.
No matter what medium you try you will still have to buy supplies.
You're gonna find that every painting medium has its quirks and learning curves. I learned acrylics first, then oils and watercolor concurrently. If you're impatient and want the ability to get rid of mistakes fairly easily, acrylic is your game, but it's more difficult to blend colors when they dry so quickly. Plus acrylic is shiny, usually, so if you're going for a matte look it's not for you. And if you're making a lot of mistakes your paint is gonna end up thick.
If you're a planner and you have a fairly steady grounding in color theory, and you have a steady hand, watercolor could be for you.
The computer is nice. But the computer won't teach you color theory. The computer doesn't teach you how to paint either. What teaches you is physically seeing your progress, and being able to go back to it and grow upon it. From making your own color wheel, to grids seeing color overlay, washing and mixing colors, etc.
