I bought one from the early campaign. As a thinking/planning device I write tens to hundreds of pages per month on paper and was intrigued by the focus on the writing experience of this product. And it is a good product- between the surface, the plastic pen tips, and the device software, provides a good enough writing experience. However, I found that my recall when using the device became zero. The loss of the physical process of reviewing and paging through written pages was unexpectedly significant, and "paging" through the digital pages did not help. So it sits unused. I should sell it.
