I have a feeling that if they plug that hack hole, it will be to put ads on the regular Kindles too. Given the limited price difference, I don't seem them selling both Wifi versions for too long. I'm not even sure I'd care. Ads are better than dead people, and while I enjoyed the novelty of putting my own screen-savers on my Kindle, I rarely even notice them anymore (this is mostly due to my inadvertant use of the "close the cover" method of not seeing screen savers
)
