Earlier this year Microsoft announced the latest version of its mobile operating system, Windows Mobile 6.5, a relatively minor update focused on changes to the user interface and its touch-friendliness. But while the first Windows Mobile 6.5 devices are not expected to arrive until the second half of the year, it appears the company is ready to show off the interim operating system next month.

According to a post on their corporate blog, Microsoft is going to deliver the kick off launch presentation of Windows Mobile 6.5 on May 11, at the start of TechEd 09. The session is targeted at both IT Professionals and Developers and will include “a cool demo and an outline of great stuff to come.” There are a handful of other WM 6.5 sessions on the agenda, including one on developing apps that use touch and gestures and another to help developers monetize their creations through the Windows Marketplace for Mobile.
