I have been waiting for this product since August, and it still not avaliable to the wide population with the exception of those that order on Amazon.com. The reviews have been so so about the product so far receiving a 3 out of 5 stars, which I should've known. It's still quite an amazing concept to take something that you drew in a sketch book and immediately put it into illustrator and make it vector art without having to scan your sketch book. I just don't understand why companies put out products that may not be fully realized. I think it is unfair to charge $200 per pen and release a product that has a lot of problems.
Anyway, the link below is about the product and there a video that showcases how awesome the Inkling is. I was sold maybe you will be too.
