exactly. any current os could fit your description in 5 years... even android and ios. the boat -metaphor is pretty bad, in real life every os has a boat of its own and only the speed they can travel in current situatuon. when situation changes, other boats gain speed and others get slower. for example ios has got relatively fast boat but its speed is limited. android has been very slow until recent hyperspeed, and symbians boat has been slowly getting slower and slower. the problem with your logics is that it is really short-sighted. what you said applies for now but what about 2016? no os can be market leader for infinite time. e: with your logic ios android would have been doomed attempts in 2008...
