The best way to protect is with a metal shell, metal protects a great deal more than plastic, even if there is metal inside it.
I've broken 3 plastic shelled reader screens in the two years I owned plastic shelled ones, and 0 metal shelled reader screens in the two years I've owned them.
But more importantly - why do I have to justify wanting a metal shelled reader? Why when I ask if any exist am I being argued with by people telling me I'm wrong and I shouldn't want one?
