The hard shell with its integration with the power management system was one of the best things about the 770. I constantly worry about my N800 vs my 770 I could throw in my pocket with my keys and everything else and not worry about it in the least. I have been very disappointed at Nokia's failure to deliver the long promised case for the N800. Their velvet eyeglass slip case which they threw in the box seems very ill suited to the N800, almost as if it was designed for something else and included as a complete afterthough. I actually feel that using the slip case increases the chance of damage, as it is so slippery that I've had my n800 go shooting out of it on several occasions.
