Wacom is actually working on a art-focused tablet that's supposedly going to be announced or delivered over the next few months. That being said, I doubt their ability to deliver something as smooth and stable as an iPad.

I like android just fine, but the Note series of devices seem to lag and glitch a bit when using the stylus. I have more confidence in Apple's ability to refine the technology. I also happen to like my current iPad more than any other mobile device I've used.
