I detest spam! I used the reader for 3 years and always downloaded to my laptop and then transferred books to the device. MY BIG MISTAKE??? I recently connected to the wifi to download a book direct and got spammed with ads on the bottom of the screen and in the default power off screen. Also lost the ability to turn off the wifi, and who knows what else. I am not going to tell you how to fix it... This is absolutely bad customer relations and I will never buy another Kindle reader.
