yeah, i'm using the kind that's more of a drawing pad (i guess the word tablet is a bit misleading, hahah).
i strongly recommend it!! even if you start out with a cheap little one to get a feel for it. i mean, yes, keep at pen and paper for sure (i think i've got a sketchbook in just about every open spot on my desk right now, just in case) but if drawing is something you're really interested in IMO it's worth it.
practice makes a WORLD of difference; i've been drawing for about ten years now by my guess. keep your old art: in a few years, if you keep at it, you'll love having the old stuff around. it's particularly helpful if you're worried you haven't improved; looking at them side by side really shows how much you've grown since.
