I actually started trying to “sketch” using the tablet. It takes a little getting used to and I don’t think it’s quite as intuitive as regular pen and paper, but with some practice, you can achieve some pretty decent results.
This is a sketch I did in about 30min usning Photoshop CS and a cheap Wacam Graphire tablet.
I hear that the Intuos line is waaaay better, but I haven’t seen for myself yet…
