Amazon's eBook reader, the Kindle is no longer the only electronic book reader available for the electronic book aficionados. A while back, Barnes and Noble had introduced the Nook and more recently the color Nook, the eBook reader for those who believe that pictures are worth a thousands words.
Besides the Kindle, look for our books on the Apple iPhone/iPod/iPad (via the iBookstore), Kobo(the eBook supplier to Borders).
