I remember when Amazon started selling the kindles. I thought to myself no one would spend close to $300 or $400 on something to read books. Well a few years later, better technology and a huge price reduction, bam they are everywhere! .
I love my ereader. I dont have a kindle I have Pandigital Novel 7. Might be the greatest purchase I ever made. They sell for $150-$199 but I got mine at kohls after xmas for $54 total including tax. I went with the Novel because it had wifi, full color, plays videos, music, epubs and pdf books and you can search the web and check email. It even has an android operating system that can be rooted to be an android tablet similar to an ipad (obviously not as fast but 1/10 the price)
Its also connected directly to Barnes and Noble and very easy to buy or get free books. If I root the system I can even use the kindle app and get books from Amazon!
