The first link tells us what Gartner is looking at: astounding mobile growth. Double the unit production for premium smartphones by 2016, reaching 1 billion premium phones a year.Tablets and other mobile devices have similar growth figures. I challenge anyone to find similar growth patterns in consumer electronics not even considering it´s a sustained growth in an already massive market.
The second link has a pretty graph with current shipped units, and the stale growth of the pc market.
It doesn´t even matter if good old gamer like you and me don´t consider true gamers all those casual farmville lovin people. The market does, and the market is lord of all.
Now the third link is the funnest of all. I think blizzard heard about it.
Anyways the point is, and i do believe i´m not contradicting myself, pc gaming will be important because its a steadily yet slowly growing market niche. But its relevance will be overshadowed by a much bigger, faster growing market.We´ll still be there, just suffocated by bird throwing retards. Perhaps this will lead to mobile gaming refinement or to the masification of retarded gaming, who knows, but Gartner is just following the growth trends in mobile and the pc market stagnation.
