I followed a link at the bottom of this article to a product I'd never heard of before, Supernote [1], and something there caught my eye. Namely on the accessories tab, there's a link to a LAMY Series stylus [2]. For those who haven't heard of LAMY, they're a pretty big name in the fountain pen world. The page is pretty light on the details, but AFAIK this is the first ever collaboration between fountain pen giant & writing tablet. It even has their iconic pocket clip design... Definitely piqued my interest.
Although interestingly, the tip of the Supernote pen that comes with the A5/A6 series looks more like something that would produce more of a pen-to-paper feeling with its 0.7mm tip.
