The original ebooks were plain text files with no formatting other than paragraph breaks and word wrap. That was it. No bold or italics or anything else other than plain text. And the early readers of ebooks were very happy to get them and read them.
Today, no matter which format you get and no matter what you read it on it's vastly more sophisticated, so hating a device or format that doesn't give all the features one has decided are "essential" seems to me much about vanity and showing off how refined one's taste is.
We're living in a reading golden age! We have so many good choices, with no bad ones, of devices, formats and options that there's something for each of us. There isn't much wrong with any of it. Let's appreciate what we have.
By the way, I referenced the plain text of the early ebooks but I might have gone back a bit farther for a more glaring contrast. Until the 10th century words in english were printed without spaces between them. Let'shearitforspacesbetweenwords!!
We've got it so good these days.
