My bad; I hadn't realized there was a mobile version. It's only $10? I was thinking about getting a tablet, so this is certainly something to look into. Is it easy to import/export back and forth between a tablet and computer?
Somewhat. If you use the free Creative Cloud service, its stupidly simple. Otherwise its a bit of a two step process.
Is there a specific tablet you would suggest?
My only concern is that, though Blender and GIMP give professional results, you are going to have a good month or two of hard work in learning enough about these software to become effective in a workflow pipeline. By that time you will still be on fundamentals for the most part. You need to estimate if this will allow you to keep pace with all that you have in the course or not. Best case scenario, in my opinion, is that you will be scrambling with at least twice the workload to adapt Blender and GIMP to a course not designed for them.
I'm not in a rush to learn everything at once. Doing that would probably bring poor results. Right now I'm trying to focus on C#, but I'll most likely watch some Blender tutorials on the side.
