I can't comment on that much on buying proper from AMZN itself since I've been vastly cutting down on purchases.
But wrt the Kindle, mine has never ever had been connected via wifi. Everything is dumped straight from the connecting PC. Strictly speaking, epub/mobi is such a static format that planned obsolescence is never an issue and if you don't connect to the internet security isn't an issue wrt to the Kindle either.
@switchingsocial @SlightDashOfColour no, but you can use calibre to convert it.
Yup, you can still partake of the ecoystem legally if you so wish, and the DRM is trivial to strip. I suspect at this point Amazon is offering DRM only as a fig leaf for the publishing houses.
@SlightDashOfColour @switchingsocial oh! Didn't know about the striping. I noticed some é-books for sale are DRM free as per request of the author, though.
@SlightDashOfColour
Thanks for the feedback!
It's a fair point that the Kindle can be used to view certain non-DRM files, though Amazon doesn't promote it in this way.
Just one thing though, as far as I can tell Kindle doesn't support epub?
