I always take the digiplayer, and use it on every flight that offers digiplayer. I usually travel with a laptop, cell phone, and an iPad, but using the digiplayer is way easier. My only complain is those players dies very fast, and need to be charging all the time. May be they are getting old.

Frankly I think one in-flight item that DL beats AS hands down is their seat back IFE system, which has a much bigger selection on movie and music, as well as a great flight status program.
