Yeah so I'm considering getting the 13HD cintiq tablet..
Because I'm going to be animating more, and I think I would be able to work faster with a tablet like that over my intuos.
The disadvantage of what I'd like to call "blind tablets" (because there is no screen on them you just draw and look at your monitor rather than your hand) is that there's a lot of guess work. If you use a tablet then you should know what I'm talking about, and what I'm referring to is how say you're inking a sketch: You have to draw a line ctrl+z draw line ctrl+z draw line ctrl+z draw line, good!
Because I am not actually LOOKING at where I'm directly drawing there is a lot of guess and check in order to get the line to be drawn in the right place.
It works, but it wastes a lot of time. I want to be able to work faster!
