As you probably expect, Amazon is having some killer sales this weekend. There's not much in the way of tablets and ereaders at the moment, but there is one exception. You can get Amazon 9.7" Kindle DX ebook reader for $259. The price is good through Monday.
This is a pretty good deal; I wouldn't have bought it at the regular price ($380), but I have to say that I am really tempted.
Now, this is the model that was released last year, but there's no sign that Amazon plans to discontinue it. My current guess is that Amazon will keep it around much like they are still selling the K3.
