The Intuos 4 models come in three sizes: small, medium and large. They weight less than its predecessors and are thinner too, so it's easy to carry them in a case.
Even for the $199 price on Amazon,
Still, its design and surface is not as rough as previous versions and looks to enhance ergonomy. The ambidextrous capability is always a plus. The touch ring is one of the best features, it takes its time to get used to it but once you do, it feels comfortable as ever.
However, these Wacom models had one particular default issue with the USB port manufacturing and pen that came defective, that even forced the fabricant to replace the tablet per customer complaints and requests. That's why you can get a refurbished model as low as $139
Beware also of the pen nibs. While the Intuos 4 models come with their pen holder, the nibs wear out too fast for frequent use. If you work 6-8 hours daily with your device, you'll know what I'm talking about. You'd have to spend an extra dollar or two for new pen nibs from time to time.
So now you see that it's not all bright, shiny and rosy when buying an expensive tablet if you're a beginner or struggling artist for the sake of it :-)
Still, if you have fallen in love with this model of Wacom tablet and feel like you can afford it, the refurbished PTK440 models have turned out wayyy better at a better price.
