As I have said before the simplest designs are always the best, this is definitely the case with the Bookmark II.

The Bookmark II is a colorful rubber band that you wrap around the page of your book, it has an arrow which shows you the last line you were reading, just move the rubber band and the next time you pick up your book you will be able to continue from the last sentence you were at.

I think it is a great idea, unfortunately there are no details on pricing or avaibaility as yet.
