I tried searching and thought it might already have been mentioned in one of the Dreamliner or 777 discussion threads, but I couldn't find anything.
Since this is FT, there must be a thread about this already? None of the recent IFE threads that I found mention this.

Mod(s), please move to the appropriate thread.

I was recently on FIN 749 and there is a nice upgrade (IMHO) to the IFE user interface. It also mimics some of the colour palette of the website and even uses the same red airplane "processing" roundel that the website uses.

No longer is there a same model type of the aircraft that you're on with your seat number when you board... it now shows nice pictures of the destination city.
Then when you touch the screen, it displays a selection of 20-ish (I didn't count the exact amount) languages to choose from.

There are a few quirks about it, and some things take getting used to, but I think it's quite nice. There are also verbose instructions on airport terminals, transportation from your destination airport, etc. There are even full-blown terminal pics that look exactly like the ones in EnRoute magazine. There is even a section where you can read more about every type of aircraft in the fleet, with a 360 view.
And, there is a section where you can look up things to do and places to go in the destination city.

I took pics with my crappy phone and will upload them when I have time... but if others can upload their pics, by all means...
