Every time I have been on a long haul international flight and sitting in Economy I am thankful for the IFE. I have a laptop with moved and a DVD player and such. However, on every long haul flight I have been on,. the person in front of me has recline all the way to the point where there is no room for me to open my laptop enough to be able to view it. Mine you, I have a 12inch laptop, not very big.
When the person in front of me reclines, the little IFE screen is in my face and about the only thing I can see the whole flight. Thank god its there!
