Looks like a case of good business sense, but which operating system will they adopt for their smart phones?

For Nokia, smartphones now represent around 50 percent of Devices &Services (D&S) revenue, and with continued share loss accompanied with pricing pressure, analysts expect this to significantly affect Nokia's ability to grow revenues in its handset business.
"Persisting with the Symbian OS going forward could result in Nokia's smartphone share declining to as low as 23 percent by 2013," Credit Suisse analyst Kulbinder Garcha wrote in a note to clients.
