1. Has anyone here used it to an extent?

If so,
2. What do you think of it? Is it as manageable and smooth as it claims its workflow is?
3. Are the tutorials reasonably understandable to a Photoshop semi-novice?

The reason I ask, is because I remember giving it a try before I started using Photoshop, and was completely bamboozled by it.
Now, I've decided to maybe give it another try, but I'd rather hear the community's opinions on it.

Well truthfully I've never used it, but it's free and looking through the tutorials, it looks like you can do a lot and probably learn a lot just from the tutorials. If it helps, I'm going to start using this after I get my computer working
