After reading this NY Times piece, my desire to own a Kindle just got set back a few years:
This morning, hundreds of Amazon Kindle owners awoke to discover that books by a certain famous author had mysteriously disappeared from their e-book readers. These were books that they had bought and paid for—thought they owned.The rest is here.
But no, apparently the publisher changed its mind about offering an electronic edition, and apparently Amazon, whose business lives and dies by publisher happiness, caved. It electronically deleted all books by this author from people’s Kindles and credited their accounts for the price.
Update: There's even more here.
