Addiction is an important component of life, sad to say. So the idea that a tablet or smartphone can replace the intense experience of a game system is ludicrous! Playing a game, any game, on a tiny-screened hand-held device is just not the same. Ask any gamer.
Remember, its not about having all the marbles, its about having all the “best” marbles. Thus the struggle to possess the best “system” continues and the suggestion that any “one size fits all” solution is just a bad idea.
