I picked up a couple of travel books at my local 20%-off going-out-of-business Borders today. Hefted them in my hand. Then looked them up on my iPhone and found that their Kindle/iBooks price was 50% lower than the Borders retail price.
So I left the store with no books, but with a pretty good idea of why Borders is bankrupt.
A wistful day to be sure. I remember twenty years ago, when the arrival of Borders in my midwestern city was akin to a religious experience.
