The $139 model doesn't come with G3 wireless (so on the $139 version you can't download books anywhere), just WiFi and of course no color screen yet. But it does show just how quickly the prices are falling. Books-a-Million even had the Sony eBook reader on sale last week for $99 (and promptly sold out).
I think, this Christmas day, Amazon better be ready for some major traffic. As I predicted before, I think $99 is the price point where parents will start buying eReaders for their kids. And I think, we'll see this price as the entry point for most eReaders by Christmas
I know I plan to have several free short stories up by then. Hopefully, it will be perfect timing to start building some readership.
