I've always wondered why "candy bar" style phones, especially Nokias, aren't created with a concave front face. To me, that would fit one's face much more comfortably - one of the reasons I feel it's easier to talk on a clamshell phone. Nokias are often flat, or worse (like 3360, 6360, etc.), they're convex! The center is thicker than the tips. It's like putting a ball against your face and trying to make it fit comfortably. Any thoughts?
