Right now my K3 is running around naked as the day it was stamped in a factory in China.
My K2 was almost (except when reading at home) in an amazon case. Now I'm less a case fan since the death of my K2 came from a drop from the counter, while in it's case. Hit the side NOT protected, busted the E-ink. Ah well. new Kindle is nice

but yeah the call for a case is lessened for me now.
