One thing I find annoying with the new flight map is that at take off and landing, the map reverts to a satellite style view of the ground so you can see exactly where the plane is at that moment....but they overlay it with the stupid text saying how fast the plane is travelling so you can't see the map.
My gripe with what is an otherwise excellent system is the 10 minutes of garbage/in-house advertising you have to endure after take-off. It's one thing on a 12 hour flight but on the way back from Manila it can take up a serious amount of the available time to watch or listen to anything.
