A comment on cases:
I bought a lighted Kindle cover for my daughter. I love the integral light and unfettered access to the top of the K3. I cheaped out for me, bought something cheaper, and regret it.
I seldom need a light. But when I do, I've found it a hassle to tote around separate gear when it could all be self contained and powered by the K3 lighted cover.
Now I have two cases and two lights which I will have to return if I elect to get the K3 lighted cover. In the end, adding in return shipping costs, I will spend much more than I would have if I had not cheaped out in the first place. You would think I would have learned my lesson by now. But no... I continue to have to learn the hard way!
I'm in the returning process now.
