The TSA released a statement regarding the new changes:
"Passengers flying from international locations to U.S. destinations may notice additional security measures in place. These measures are designed to be unpredictable, so passengers should not expect to see the same thing everywhere. Due to the busy holiday travel
season, both domestic and international travelers should allot extra time for check-in."
According to a post on Twitter, the new security measures will add body searches and the electronic ban will be for international flights only. The New York Times also reports that passengers will not be allowed to move from their seats an hour before landing, when the plane begins to descend.
Although this ban may only be temporary, it comes in effect just as passengers from all around the world will be heading to Las Vegas for CES 2010 and can expect a boring flight. A lot of passengers will be upset over this ban, when they won't be allowed to use their new iPod or Zune HD that they got for Christmas.

In the wake of the terrorism attempt Friday on a Northwest Airlines flight, federal officials on Saturday imposed new restrictions on travelers that could lengthen lines at airports and limit the ability of international passengers to move about an airplane.
The government was vague about the steps it was taking, saying that it wanted the security experience to be “unpredictable” and that passengers would not find the same measures at every airport — a prospect that may upset airlines and travelers alike.
But several airlines released detailed information about the restrictions, saying that passengers on international flights coming to the United States will apparently have to remain in their seats for the last hour of a flight without any personal items on their laps. It was not clear how often the rule would affect domestic flights.
Overseas passengers will be restricted to only one carry-on item, and domestic passengers will probably face longer security lines. That was already the case in some airports Saturday, in the United States and overseas.
The restrictions will again change the routine of air travel, which has undergone an upheaval since the terrorist attacks in New York and Washington in September 2001 and three later attempts at air terrorism.
Soon after the attempt on Friday, travelers at airports around the world began experiencing heightened screening in security lines. On one flight, from Newark Liberty International Airport to Little Rock, Ark., flight attendants kept cabin lights on for the entire trip instead of dimming them for takeoff and landing.

of my cojones, I did not have anyone stop my ipod from being used - heck, I had internet & USB port in my seat with internet access available once we reached 10,000 ft. It is still too early to see what happens.
