Why Windows will likely surpass Android in the tablet market.
Microsoft's decision to put touchscreens on laptops and desktops has pretty much guaranteed them a larger market share than Android in the tablet market. Making tablets a subset of desktop devices was a very clever move. The fact that developers can target laptops, desktops, and tablets all at once with little or no optimization for each type of device, makes the platform much more attractive than Android. With Android, you can target phones and tablets, but it requires significant optimization for each type of device, and Android has no desktop presence. Android's reliance on Java becomes a greater liability as productivity and performance demands increase as they do on tablets and desktops. Android's inability to scale up well will prevent it from ever dominating on the desktop. 7"-8" Windows RT/8 tablets at $199-$299 will likely start a dramatic shift in market share towards Windows tablets. Hybrid Windows laptop/tablet devices (like the Yoga) will fail, but it doesn't matter. It's the small tablets and, indirectly, laptops that will secure Microsoft's tablet market share.
I suspect Andy Rubin stepping aside was partially because Google realized that Windows has a better shot at dominating tablets than Android, and they basically missed a golden opportunity to end Microsoft's desktop dominance. Android was never designed with tablets in mind (let alone laptops and desktops,) and Andy Rubin often seemed dismissive of tablets. That could cost Google a lot in the long run. When Android loses its ground in tablets, all it will have left are smartphones. If Microsoft dominates tablets, many people will want to use Windows Phone smartphones for better integration, and developers will start to lose interest in Android. I predict Android will lose a massive amount of market share in the smartphone market because of this. (Apple will probably still dominate the high-end tablet, phone, laptop, and desktop sales.)
Microsoft may have been late to the current tablet market, but they played their hand perfectly. Microsoft scaling their OS downward, rather than upward, will pay off in the long run.
