After six weeks without product because of booming demand, BooksonBoard now once again has Cybooks available, this time with increased on-board memory (easily allowing for the storage of up to 500 eBooks) and longer battery life.

BooksonBoard (www.BooksOnBoard.com), a leading provider of eBooks and audio books, shipped the first back-orders today and has enough units to fill new demand for a short time.

At a new reduced priced of $379 (including $25 worth of new eBooks for free from BooksOnBoard), the Cybook Gen 3 Ultralight is 30% lighter than the Sony Reader and 50% lighter than the Kindle.

“Weight is very important when you’re trying to hold a piece of hardware for hours at a time while you read,” says Bob LiVolsi, CEO of BooksOnBoard, “Plus the Cybook uses the Mobipocket format which is generally available and an industry standard.”

The Ultralight North American bundle includes $25 toward eBooks or downloadable Audiobooks, premium leather case, USB charger, and USB cable.
