A lot of the kerfuffle centers on the Kindle, mostly, I think, because Kindle is way ahead in eReader popularity. Always informative agent Nathan Bransford mentions this in his Friday This Week in Publishing post where he cites both pro and anti-Kindle posts. Certainly the snarky video (made by a used bookstore) referenced in this TeleReads post takes on the Kindle by name.
As an example, this article on the Kindle jumps the gun a bit, I think, in predicting the demise of books. I think magazines and newspapers are safe until large color screen eReaders are reasonably priced, which I would think would take several years, at least. Novels are another story. How many novels really need color or a large screen? This is why fiction publishers need to figure out ebooks and fast, because e-ink and iPhone-like readers are growing in popularity.
Now if the people who love books can just learn to tolerate each other's preferences, we'll all be fine.
