Re: you really got to admire apple
The reason services are increasing is because the installed base of iOS devices is increasing. It isn't like 50 million old iPhones were retired in the last three months to balance out the 50 million new ones that were sold. Since Apple supports iPhones with updates for far longer than any Android phones they hold their value better and almost all have second (and probably in many cases third) owners. Except for high end Android phones like Galaxy/Note, Android phones have almost no value after a couple years and it isn't worth the cost for carriers to refurbish/resell tradeins - instead they are recycled.
The bigger their installed base the greater their services revenue, even if their per user services revenue were to stay flat.
