Do premium carriers continue to invest heavily in hardware — in expensive in-seat audio and video systems that provide packaged offerings like hundreds of on-demand movies, television programs and video games, but need regular upgrading as technology improves?

Or do other carriers concentrate mostly on improving in-flight Wi-Fi for those passengers who prefer to use their own hardware? If so, do the airlines try to sell them licensed content like movies and video games, while somehow overcoming significant concerns by studios and other providers about piracy? And how do they address passenger discontent about slow, balky in-flight Wi-Fi service, not to mention complaints about the dearth of power outlets on airplanes?
