There were two significant announcements in the ebook world yesterday.
Barnes and Noble announced a new Nook Lite (a wifi only reader) for $149 and a lower price for their regular Nook for $199. There was also a software upgrade for the regular Nook. Both are available now with free shipping.
Amazon countered with a price drop for their Kindle 2 to $189. It is available now with free two day shipping.
The competition is great for everyone, but the Kindle is the better buy. The updates over the past couple weeks have made the Nook a much better competitor to the Kindle. But the Amazon bookstore still pulls the Kindle out front.
Update: I saw that Amazon has their refurbished Kindles (which come with a same as new warranty) are now $139 with free shipping. I am seriously considering getting one for my wife.
