The Wacom Intuos Creative Stylus is a pressure-sensitive iPad stylus from arguably THE foremost maker of digital styluses and drawing tablets. They had previously released the Bamboo iPad Stylus to good reviews, but the CS is the first iPad tool from Wacom to feature pro features, design, and connectivity. It was not the first pressure-sensitive stylus to be released to the market, but with the company's reputation for great art pens, this stylus was highly anticipated.
I personally don't think the CS produced anything groundbreaking or new compared to the few other pressure-sensitive styluses that have been produced so far, but it is solid and performs well. It stands its ground against its competition and is one of the best styluses you'll find in the market so far.
