Ballmer admits Windows Phone 7 is still struggling to make an impact

Microsoft CEO took the stage during the company Worldwide Partner Conference, which is held this week in Los Angeles, and revealed some interesting bits about the company mobile platform. Steve Ballmer admitted that Windows Phone 7 has not been particularly successful yet and in a year its market share has gone "from very small to… very small"

And while those are hardly the words Microsoft partners were hoping to hear, Ballmer remains optimistic about WP7 prospects. Expectations are that more users and developers will be drawn to the platform in the years to come and it will be able to compete with the Android and iOS behemoths.
