"The Wi-Fi Paperwhite will be available for a relatively cheap 8,480 yen ($106)" actually now $95 at today's exchange rate (JPY is down lately).
So is there a way to pick these up for $95 in Japan. And then hack them over to English.
See below for link. Price is 7,980 Yen = $90.
And when they release them in mainland China some year those should be even cheaper...
