It seems that the sales people have added a multitude of unwanted functions: Dictionary, highlights, notes, and so many others.
When I attempt to turn the page it will frequently jump into some unwanted function.
And often it will leap to a random page, leaving no way to get back to where I was. And the functions are entirely different between books and magazines.
Just yesterday I lost my place in a book and spent half an hour trying to get back. Eventually I deleted the book entirely and abandoned the Kindle.
From now on I'll be using a tablet to read on. Additionally the tablet can display PDF's which are my main interest.
