+ The cover can be fairly easily "cover", fits perfectly and is absolutely non-slip in hand. + The recesses for charger, headset, camera, etc. fit perfectly. + The pushbuttons for standby and volume buttons require (of course) a bit more pressure, but provide for a stable handling. + The cover is surprisingly thin / flat, making the device not so clunky. I can about the protective effect of a fall say anything yet (thankfully). + The standing on the edge of the display to protect it from scratches when the unit times "upside" is stored.
Overall, the sheath makes a very sophisticated look.
