To me, this question seems to be off topic for ebooks SE (the user also asked a similar question on the physics se). What are your thoughts for questions related to the technology behind ereaders? On or off topic?
I'm on the fence for this one. We allow some questions about ebooks and the underlying technology. Should we do the same for ereaders? It may open up the site for more activity. The site, however, is ebooks SE, not ereaders SE. Perhaps where we can be lenient towards ebook technology, we cannot show the same leniency for ereaders.
