TSA/FAA won't step things up. This is an incident involving a budget aircraft taking off from Somalia, a known region of terrorist activity. The air security in that region is comparatively low to places such as America, and the incident most likely couldn't have occurred on an American outgoing flight.
While the FAA may move to make sanctions on flights going to/from Somalia, they have no reason to ban electronic devices considering they already scan them and can detect bomb residue.
