I don't think there will ever be that many people using e-readers. Not for a long time at least.
Don't be too sure. Amazon and Barnes & Noble are the two largest (as far as I know) online booksellers, and, for both websites, their respective ebook readers are their best selling products ever. Furthermore, they both sell more ebooks than they do physical books. I'm sure it'll be a while before physical books are genuinely hard to come by (that would be my definition of "death" ), but it won't be long before ebooks are the dominant medium. Brick and mortar bookstores have been steadily declining for a while now (Borders has already gone under) and, once those go, physical books will be done.
If I had to make a guess, I'd bet that retailers will eventually stop stocking physical books and move to a drop-ship print-on-demand model. Physical books will still be available to those who want them, but at a higher cost. Ebooks will be the mainstream product, and physical books will be the niche market. Or so I predict.

Paper books will not die for quite some time I'm sure.

I guess it depends on what you mean by "death."

Of course an online bookshop is going to sell more e-books than physical books.

I'm talking about the "Amazon sold more e-books than physical books in 2010" argument.

Amazon being so successful at controlling the ebook medium makes me uneasy.

No. I just don't think this spells the end of physical books at all.

Assuming you're right, that will still wreck the business of physical books.

You are right, of course. But all the rationalizing in the world doesn't make me happy about it.

The selection is awful, the interface is awkward, and it requires bizarre DRM installations.

To be fair, Overdrive's problems are software issues, and not inherent to the business model.

I definitely agree; I'm just irritated they're sticking with Overdrive. Ebook libraries make sense. *NM*
