I don't know, I don't know .... not sure if I want to send my Iliad away EVER again; I'm just too, too used to it. I can live with the current battery life and as far as the back plate is concerned - isn't it cooler to own one of the original Mk. I Iliads, "the ones with the funky back?" Isn't that what the Ebay crowd will respond to when I sell it ten years from now?
