As I recently traveled on the Frankfurt - New York JFK route with Delta, I have to share my impressions of Delta's Business Elite Flat-Bed seats. As you can see above this relatively new seat uses the "pod" design and does provide the passenger with a very wide armrest which is large enough to leave your food tray should you feel the need to get up while in the middle of your meal.
You will aslo find a regular power source as well as a USB port which should be plenty enough to charge your electronic devices while aboard. The In Flight Entertainment (IFE) system is a pleasure to use as the user interface is very responsive (compared to Air France's extremely slow IFE where there's almost a second lag after each press of a button).
