No one could challenge the strong hold of Apple in Tablet and smartphone sales. Not even when the mighty google put its weight on Android. Apple created the smartphone and the Tablet market on its own and continues to keep a firm grip on it.
While this is not going to change completely with the Windows 8 based Tablets and smartphones, but, there are few things that can work in favor of Windows 8 based Tablets and smart phones. First, the ecosystem of Windows 8 machines, Tablet and smart phones makes a much better combination than an ecosystem based upon apples “closed” solution, where, its tablets and phones can not communicate with other operating systems.
With a decent user interface and fast response time, the Metro in Windows 8 has a decent chance to grab some market share. Only time will tell if this is true or not.
