Interesting article from Business Insider.

The smartphone wars could look a lot different soon if giants Research In Motion and Nokia align themselves with new platforms.
Nokia is reportedly considering aligning with Microsoft’s new Windows Phone 7, which would be a HUGE win for Microsoft. Windows Phone 7 got good reviews from critics, but has not been a big commercial hit. Support from Nokia could be very helpful.

Meanwhile, Research In Motion is in the process of moving to a new BlackBerry platform called QNX, which can reportedly run Google Android apps. If the BlackBerry PlayBook and forthcoming BlackBerry smartphones can run Android apps, that could be a big boost for Google’s mobile platform.

Here’s a chart of last quarter’s mobile smartphone market shares (left) and a hypothetical chart (right) of what the new alliances might look like, all else being equal.
