The free software fragmatism is like evolution; no matter how powerful the T-rex was, lesser species survived the catastrophy to become the dominant species.
Microsoft and Apple are strongholds that will rise and crumble because they are strongholds, and Android, which builds on the "OMG Linux will never be user friendly because of x, y, z!"-'technologies', somehow became domminant because of what exactly? -> fragmentation, leading to innovation. No matter how crappy, if Motorola and Sony suck, Samsung will make up for it (and vice-versa).
