No idea what the author was referring too. Maybe the new Kindle Fire?
As opposed to my iPhone, iPod Touch, iPad and iPad2, all of which I've taken down rather horribly with just the normal apps (typically frozen, sometimes insta-reboot), not even counting things that bad programs _I_ wrote were doing.
I've just been too lazy to change the cover, and it's not been overly inconvenient yet. Amazon, to their credit, offers a refund. Perhaps this blogger is using a non-lit cover and is unaware of the issues with it?
