To echo some of the other points here, I think the price is going to hurt it. Especially if the driving appeal is a product that allows for reading and note-taking together.
Honestly, part of me wonders if more distractions really is better anyway. When I read, I like to highlight and then circle back to process those parts that stood out. I separate my reading and note-taking for the most part. This may just be my own quirk.
Regardless, if the driving interest is a device that allows for this kind of potential, then I see an opportunity for another company to create a device that serves this function with limits on what else it offers (not a full fledged smartphone per se, but a smart reading device perhaps).
And at a significantly cheaper price. Just a thought.
