Is this the economics thread or what
The thing is, this product has critical bugs when it comes to usage scenarios that can really make the device stand out from all other devices on the market (like taking notes and annotating pdfs). The bugs have been discovered by users years ago but there are still there. In this way the device loses its advantage over other products on the market and can't really become a big commercial success. The unique usage scenarios are so buggy they can't really be relied upon. Onyx had to try and stick to their strengths (like taking notes and annotating pdfs) but I guess the managers were taking a nap during these marketing classes.
I think ONYX were really close to making that killer product that could make them a big company but they seem to have missed their chance.
