Isn't this the plan where the store that sells the Kindle gets a cut of all purchases made thru said Kindle? So that kickback expires after two years. Sell them a new kindle and reset the kickback clock. There's always a new reader coming out with new features, more storage, better display, etc.
This reminds me of that thread a year or three back where it was pointed out that book publishers need to realize that they're in the business of selling content, not paper. Paper is a content delivery/storage/display method. Kindle is the new paper in this scenario.
Paper books had a pretty good run. Over 500 years by my math. Now the business model is changing. Bookstores can find a way to change with it or they can bleed money until they go bankrupt. Their stubbornness isn't going to change reality. If they want to keep selling paper, they need to shift their physical inventory to publications that can't easily make the transition to electronic distribution. Large format books with lots of pictures. Art, atlases, photos, etc. Take the leftover space and stock it with readers (only from companies that will give you a kickback) and accessories. Put in a coffee/tea counter, comfy chairs, fireplace, etc. Fast WiFi, charging stations for devices. Have "meet the author" nights and "get the most out of your reader" nights.
