As if those artificial limitations (really? one ebook for one user?) weren't bad enough, you can't "return" books early. So if I finish the latest [insert popular novel] in a day but my lending period is 2 weeks, the next person on the waiting list won't be getting it for another 13 days because of yet another artificial limitation.

It's been pointed out by many librarians in comments to articles/blog posts about the situation that the average rate of loss/wear and tear for physical books may be enough to warrant buying a new copy after 26 checkouts, but that the more suspicious thing is that 26 checkouts of an ebook for 2 weeks at a time back to back (and again, no early returns) is exactly one year.
