makes sense economically, maybe not now but in 5 years. Afterall 5 years ago Smartphone/Wifi mobile internet was very uncommon to say the least, which, has become the norm. thinking creatively, maybe the inflight WIFI will be inflight entertainment alternative, such that pax can choose to have on demand movie/music etc from the Wifi database. Such that CX can save significant cost by eliminating the hardware but continue to offer the software via Wifi (no weight).
