Cheers for the replies folks! I've noticed myself that going from the newer ICE to the old styles is a bit of a let down. I once flew BHX-DXB-DAC and back, outbound the BHX-DXB leg was on a shiny (at the time) A6-EG* model with the widescreen ICE (this was in 2009 so the best they had at the time). Both DAC flights were on an older B772/773 with the old IFE and the contrast was noticeable. Worst of all, on the DXB-BHX leg we were seated on a newer plane with nice new ICE, then it went tech and we had to be shepherded onto a spare aircraft...with the older system! Still excited for the trip, fingers crossed for a new one as they look amazing and keen to try them!
