Is there a way to get rid of the time display and the completion-meter on Amazon's Kindle?

I have not bought a Kindle yet but was interested in one. Then today, I noticed this picture in the Wall Street Journal.

I notice that as you read the “pages”, there is a bar across the top displaying the time, and a completion-meter at the bottom.

When I read a book, I do not want to be constantly reminded of the time. What a way to ruin a book.

Then there’s that completion-meter at the bottom. I don’t want to keep thinking “Oh i’m 72% through the book”, etc., while reading.

Is there a way to git rid of that horrible clock? And the completion meter?
