I finally took the plunge and bought my first 'real' tablet (I had an ancient Bamboo years ago, but it sucked) - a Huion Kamvas 13. It was a pain in the a$$ to set up, but this thing is flat out amazing. Lightweight, plenty of screen space, and the distance between the writing surface and the actual screen is so tiny that it really looks like pen on paper.

Well worth the money.
