I don't see the new MBPs getting rounded edges. My pre-unibody's edges don't bother me. And wouldn't a MBP with rounded edges look silly when it was closed???
He means the part on the edge of the palm rest. Not the shape when closed or the curve under or on top of the lid. The current Macbook's edge is no more rounded than the current Macbook Pro's. They are both "sharp".
