I still hate the idea of not being allowed to buy/sell used books, and the potential to spy on you, which everyone from kindle to Wacom has decided to do. Paper and paper books are just the way to go for now
There is a “send to kindle” function which allows you to either use a desktop application, or set up an email address you can send .mobi files to!
Highly recommended if you get tired of plugging in - thats why I swapped from my old Kobo to a Kindle.
