We’ve talked about the Intuos4 before, and the featureset is one of the most complete for any tablet in the industry, short of the Centiq.  Ben Long has a great review up on CreativePro about the Wacom, complete with information about the various Intuos4 dimensions and features available.

It always surprises me when I discover that an otherwise gear-laden photographer lacks a Wacom pressure-sensitive drawing tablet. I forget that not everyone understands that a Wacom tablet is an essential piece of post-production equipment, like a computer. For that matter, anyone who works with image editing, painting, or illustration software needs a Wacom tablet. Graphic designers, illustrators, visual effects artists — if you ever brush on a paint stroke, it’s silly to use a mouse.
