Windows Mobile 6.5 was never part of Microsoft's mobile phone roadmap, and has been described by its chief executive, Steve Ballmer, as "not the full release [Microsoft] wanted" until the multi-touch enabled Windows Mobile 7 (now replaced by Windows Phone 7) arrives in 2010. Version 6.5 is an upgrade to Windows Mobile 6.1 that was released to manufacturers on May 11, 2009, and the first devices running the operating system debuted in late October '09. This incremental update includes some significant new added features, such as a revamped GUI, new today screen with vertically scrollable labels (called 'Titanium');
