Forget the 'cool' no edge look, a nice 3mm or so of Ti, stainless steel, even maybe nylon bezel would make carrying the phone in a rubber or plastic case superfluous. We already know that the cool glass-to-the-edge look is why most phones are encased or cracked now, but you rarely saw a cracked N900. I think any community project should aim for maximum longevity vs racing past the current industry trends at making phones a profit center with replacement required once a year of the thin all-glass designs.
