It's kind of crazy that the cover for a $140 kindle costs $60.
I'm looking at getting upsold by $110 on a $139 device. First it was "well, $50 for 3G everywhere forever is probably worth it". Now it's "$60 to keep my now-$189 Kindle nice and to have a light that doesn't suck is probably worth it."
If there's a review for the new one that says, "This doesn't suck," then there's probably a review for your previous 3 that says the same thing...
