I thought a new feature for 11.2 was autoupdate in the background. Did not work for 11.3.
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?
