Again, if this is your first time shopping for a tablet, then I would recommend trying out the Bamboo line of products before considering the Intuos.
I enjoy the Intuos4 tablet, and I would recommend it to any serious graphics designers/photographers/animators/etc. This is a worthy investment and you won't regret it.
With a new design and features inspired by members of the professional creative community, Intuos4 redefines the pen tablet experience. Featuring Wacom¿s new pen tip sensor technology and 2,048 levels of pen pressure sensitivity, the Intuos4 pen captures the most subtle nuances of pressure, allowing you to dynamically adjust exposure, brush size, opacity and more. User-defined ExpressKeys activate frequently used shortcuts and modifiers. The finger-sensitive Touch Ring quickly controls up to 4 different functions such as canvas rotation, zoom, scroll, brush size and more.
