I have a tablet, but make relatively little use of it. But then I use CorelDraw as my program of choice; I have a strong preference for vector-type drawing programs over the bitmap-type. It's the way my mind works.
I love not having to worry about my lines being crappy when I first draw them, because I can then reduce nodes, add nodes, smooth nodes, convert nodes to cusps, and otherwise tweak nodes. Not to mention trimming and welding shapes and all those other vector-type things CorelDraw allows.
Mine's a minority preference, judging by the overwhelming popularity of using Photoshop, or a cheaper photoshop-like program for creating artwork, over things like CorelDraw or Adobe Illustrator. But you *might* be another with the same minority preference for vector-type programs. You might give it a try, the way I've given Photoshop, Paint Shop Pro, etc. a try.
You can download a limited-time trial version of CorelDraw from the corel web site. Or there are other freeware & shareware programs out there that resemble CorelDraw the way certain freeware & shareware programs resemble Photoshop.
As an example of how I work, the first attachment shows what a drawing looks like when I first start it, and the second shows a finished drawing. (They're not the same drawing because I don't save my initial rough outlines; I smooth them in place, then save the smoothed-out version, and only then make a copy to do further detailing and elaboration.)
