This discount is on the version that you have to hook to your computer in order to update. A single $25 discount seems inappropriate for this devices.

I would rather see a discount on the free-3G/wifi version of the unit. In this product, you get free 3G for life. An ad-supported model makes more sense because you continue to receive a service in exchange for continuing to receive ads. It would also allow them to update those ads more often.

The best solution would be to discount the reader a bit *and* discount each kindle book you buy, say maybe by 10%.

Just a guess, but removing authplay.dll might help mitigate the Reader portion of this exploit. I generally do that after every Reader upgrade because a similar vulnerability happened once before. Besides, who ever uses Flash inside a PDF document anyway?
