The thing is it took Apple 5.5 years from initial conception to market for the original iPhone. Then you see all these other companies(Samsung, HTC, Motorola, Sony) scrambling to get ANYTHING to the market based on design & implementation cues from Apple's half-decade of R&D. If it took Apple 5.5 years then how would it take anything less from another less-capable company to come out with a true game-changer?
And your point being ..?
