The book updates provide both .mobi and .epub files. The explanation about which format to use says that the Send to Kindle app for desktops only accepts .mobi but that Amazon has stated that .mobi is going away. I learned today that there is a Send to Kindle web app (amazon.com/sendtokindle), which supports uploading .epub files. So, I believe that there's no longer a need for the .mobi files or instructions to use the Send to Kindle desktop app -- just use .epub with the Send to Kindle web app.
