Improved housings for electronic devices are disclosed. In one embodiment, an electronic device housing can have one or more outer members (e.g., exposed major surfaces), such as front or back surfaces, that are formed of glass. The one or more glass surfaces can be part of outer member assemblies that can be secured to other portions of the electronic device housing. In other embodiments, apparatus, systems and methods for robustly attaching a cover portion of an electronic device to a bottom portion, e.g., a housing portion, of the electronic device are described. The electronic device can be portable and in some cases handheld.
