If I was going to hazard a guess, I'd have to say that retailers are looking at E-book readers as one of the big sellers this year since e-book readers were probably the most common thing on the front of the ads. Examples? Kohls selling Literati for $99, Best Buy selling Nooks for $99, CVS Pharmacy had an e-book reader for $98.88. Radio Shack had a PanDigital e-book reader for $149.99. There were more, but these were just some examples on the first pages of some of the ads.
One of the other things that surprised me is the number of different e-book readers on the market. While the Amazon Kindle is the best known, followed by the Barnes & Noble Nook, and Apple iPad. There are quite a few others. Just for a little perspective, I conducted a quick Internet search on e-book readers and found an article on C/Net rating 75 different models. Of course there were many variations of the same brand. It basically came down to the following list of 19.
Astak EZ Reader
Barnes and Noble Nook
Sony PRS-500 Portable Reader System
RCA REB1100 eBook
The Sharper Image Literati Digital Reader

Enjoy your leftovers and
