Yeah, I don't get why phones have to be as thin and fragile as possible. They look gorgeous, but are so flimsy you need to hide them in an ugly case that undoes all the work in making them thin and pretty.
In some ways, the best design is still my old Motorola Milestone. Rubberized steel, and indestructible. No case needed. Small, better looking than anything in a case, and it had a sliding keyboard to boot. I still miss that.
