Not all devices, even those highly leaked ones, see the light of day. Some get unceremoniously abandoned on the cutting room floor. Last week, we caught a glimpse of the much fabled and sadly still-born Microsoft Surface Mini. Now we're being treated to another canceled 8-inch Windows device, the Nokia "Mercury", which would have become the Lumia 2020. Unfortunately for Nokia, it never came to be. Unfortunately for Microsoft, this could have been a better hit.
