Google to Surpass Microsoft in OS Penetration by 2016
According to the market research firm, Google will be able to increase the number of Android devices in the market from 608 million today to 2.3 billion computers, tablets and smartphones by the end of 2016.
In comparison, Windows devices are projected to grow from 1.5 billion to only 2.28 billion units, Gartner said.
The firm believes that the mobile market in particular will continue to consolidate around Android and iOS, "with other ecosystems struggling to gain traction, and, with most vendors committed to Android." By the end of 2014, three of the five top mobile handset vendors will be Chinese, Gartner said.
In the tablet market, unit shipments are estimated to be about half of the volume of notebooks by 2015, while Windows 8 is not expected to trump either iOS or Android in tablet volume and has to be content with third place.

Pretty useless, I know, but I couldn't help it.
Don't see it, Samsung is Korean and their government has not sold out to China like the USA government has.
The mobile platform has a much faster turnover time - Nokia and Blackberry was not so long ago all the rage. It will all depend on how well WP8 integrate with the corporate/enterprise structure to give both iOS and Android a run for their moneys.
Article should say, "Android will continue to be on more phones and tablets then Windows still." Maybe Windows tablets will take off and sell more than android, I doubt Windows phones will become popular.
For starters, it doesn't support the vast amount of hardware allowing a PC-builder to build their custom PC using just about any hardware.
Also, peripheral hardware like printers aren't really supported.
And real multitasking is much better on Windows. Support for multiple monitors etc...
In short: It is unfair to compare a specialized mobile OS to a general OS (intended primarily for desktop/laptop use). (Even though I personally love Android in my mobile).
Windows 8 tablet market share will surpass Android tablets very soon according to the IDC's estimate. The IDC's market share estimate is based on number of units. Windows 8 tablets are more expensive now, so it will sell fewer for now. But low cost models will come out soon. On the other hand, Android is going after the lower and lower end market at cheaper and cheaper prices.
In terms of market share based on revenue, Microsoft's Surface is selling at $999, or $1140 plus the touch cover, that's about 5 times of 7" Android tablets. Revenue-wise, Microsoft only needs 1/5 of Android's market share to beat all Android manufacturers combined. Moreover, Surface has a gross margin of 45%, vs. cheap Android devices at less than 20% of gross margin, in terms of gross profit, Microsoft makes 11 times more profit selling one Surface Pro than Android vendors selling one Android tablet!
And price-wise, Dell, Asus, HP and Lenovo are offering lower end Win 8 tablets at about $399 to $499, which is very competitive to iPad and 10" Android tablets. Lastly, don't forget that Microsoft receives $5-$10 of royalty for each Androud device sold.
