Does the ex-bmi A321 have the same content as the A380? They're both Thales systems, although the A321 still contains a number of bmi references so they look different to most people.
I found enough on both systems to not need to use my fully loaded and ready iPad. As the A380 flights were to LAX it means that there's a decent amount of choice.
The reason I ask is because I did find more I wanted to watch on the A321 but as I travelled these in different months it might have just been I preferred the content in the month I used the A321.
