A website for the Windows Marketplace for Mobile, Microsoft’s answer to the Apple App Store, has gone live with plans to include an application marketplace on Windows Mobile 6.5 devices.

The page is quite obviously formatted for mobile browsers and claims it will put “applications at your fingertips that make life more fun”. Customers will be able to use the Marketplace to find and purchase mobile applications with their Windows Live ID.

At the Mobile World Congress show in February, Microsoft chief executive Steve Ballmer announced the portal that he said would allow customers to browse and download applications using their Windows Mobile 6.5 or earlier phones, and would offer developers the opportunity to connect with Windows Mobile users.

Dedicated online Mobile Application websites being lead by Apple, Android , Nokia (Ovi Store) and Blackberry (who just opened its store last week) will soon become even more crowded, with this addition from Microsoft. Sony and Samsung are also expected to be launching their own App Stores later this year.

Research firm Strategy Analytics forecasts that the mobile content market will grow 18 percent in 2009 to £48bn.
