Interesting development in Kindle-land:
Amazon announces ad-supported Kindle for $114
It appears that Amazon will use the screensavers for advertising on these devices, which begs the questions (which I know currently have no answer) ... 1) What will happen if someone tries to install the screensaver hack on one of these, 2) How will the warranty/terms of use be different on these devices, and 3) How will non-ad devices be affected...
