Has anyone thought of building a SCREW on cover?
I'm thinking suede lined carbon fiber/aluminum panels and a leather spine, attached to the device with screws on the back. It wouldn't fall out and spaces could be cut for the buttons. Access to the SD card and battery would be sorely limited, but how many of us take out the SD card on a regular basis?
(I wasn't sure if this should be in a sub-forum or not)
