Just announced by Amazon on their Twitter feed, they will have a limited number of 2nd Generation Kindles for sale starting Friday at 9AM PST (that's noon, for us east coasters) at $89 each. That's the same eInk screen as the current nook and with built-in 3G wireless. Not only a better price, but a much better deal than the limited number of Wi-Fi only nook's that Best Buy will have as door-buster specials for $99. And you don't have to stand outside in the cold all night to get the deal!.
Bookmark this post and check back at 9AM this Friday. If the link changes for the deal, I'll update this post first (and then probably add a new post for new readers).
Update: It appears that the deal will be on the Black Friday Deals Week page, in the lightning deals at the top of the page. For now, I'm leaving the link the K2 page above, though, as that's the link Amazon used in their announcement, as well.
This is a great deal for a backup Kindle or for the additional readers in your family. There isn't any Wi-Fi, but that can be an advantage for some, as the 3G is so much easier to "set up" (in fact, the only setup is turning it on).
