One could go on at lengths as to how Emirates could have afforded this and has grown arguably inorganically into a major purchaser and upcoming major player in the airline market.
However, having said that, it is unfortunate to have to concede that the standard has been set in First Class and in terms of inflight entertainment and of course, innovation.
Airlines across the world who are not government subsidised and who do have a relatively finite pool of money will have to swim deep into consciences.
One must consider however, if there is a First Class market that can cope? So many airlines around the world are pulling First Class off the menu. British Airways are doing it to six key destinations while other airlines are introducing solely Business and Executive Economy classes to their planes. There would certainly be market however, if an airline for some reason operates full schedules to Australia for example while there is a dramatic downturn in the market and having those aircraft operate at 40% capacity. Emirates is known to offer very very cheap fares compared to other competitors and it may be on its fare "structure" rather then market realism that it has invested so much in this superior product.
The sliding doors is something that I imagined would occur on the A380-842 however, Emirates has brought this thought to advanced fruition. The First Class product and IFE / ICE as a whole is remarkable. Little technical details are known about anything though. How large are the seats? What kind of leather is used? What is the seat dimensions for the Business Class seat? Will passengers cope in 33 - 34" seat pitch over 17+ hours in Economy Class? How does the airline justify that if the seat pitch is so "small" (for that length of time anyway).
Despite all this, kudos must be given where it should be given and here at the front of the plane and in the inflight entertainment department, it must be given. I being a Singapore Airlines follower can only draw some contentment that the plane isn't flying everywhere in the Emirates route network... yet.
Anyone can fly, only the best Soar.
