I still have my K1 and it still works fine. Well aside from some connection issues. It seems to have issues calling home. I grab it sometimes to read something on it, but not often. But I have to say that every time I put it in my hands, I am reminded how ergonomic the device is. It fits in my hands like it was melded in there and the easy of changing pages was just such a pleasure. I have bad wrists and hands and still to this day, that kindle has been the most comfortable. I thought it was brilliantly designed for reading. I know many hated the shape, but the wedge just works better for me.
Now everything has to be so thin that it hurts my hands after a while, even after adding this and that cover.
And of course there is the magical sparkly bar that goes up and down. Has anyone ever decided what exactly that thing is?
Reminds me I need to charge all my older devices up again.
