Tungsten E2 Hardcase
I'm now a proud owner of a Tungsten E2 hardcase made by Innopocket. Looks fine so far: robust, lightweight and access to all important functions.
There are currently just two minor things that could be better. The mount for the belt clip makes the backside uneven. This is bad if the plam lays flat on the table: when you want to write something it wiggles 
. The other thing is that you can't wrap the front cover around which makes holding it one handed a bit harder. Does anyone know a hardcase which can do that?
