See, I don't look at it as a horrible battery problem or the cover as a fix. It was designed to be used like that. As a combination. The reader was never designed to be used only by itself. Its a package, just like its purchased, all in one retail box.
I don't compare on part of the Oasis to say my other kindles, I compare the package as it was designed to my other kindles.
I charge my kindles up about once a month. From my K1 on to the now Voyage. K1 I have to use its special charging cord as that was different than what the other kindles use.
I am not sure really why I do it, I don't use them, but I hate them going totally dead for some reason. Especially my beloved K1.
I dream of devices where the case has solar chargers in it, or painted with solar. They'd look exactly the same, and would just charge themselves.
A world where we never have to worry about charging anything ever again. And were batteries are so good they never die.
