Microsoft is working hard on Windows Mobile 6.1 and 7.0 to combat Apple's iPhone. WM 6.1 will be a minor user interface refresh that will make the mobile OS more user friendly while WM 7.0 will be the next major release.
A gallery of screenshots from the 6.1 refresh compiled by Boy Genius shows an emphasis on simplification: the screens are more task-oriented and have less clutter than their immediate predecessor. A new and clearer font adorns the UI, and new features such as zooming, copy and paste in Internet Explorer, and auto-configuring ActiveSync for e-mails are sure to be welcome additions to the platform. In addition, Microsoft is making it easier (and more Windows-like) to switch tasks by adding a standardized task manager to the platform.
As far as Windows Mobile 7.0 goes, there are no leaked screen shots as of yet, but big changes are afoot. Microsoft plans to completely redo applications such as Internet Explorer, bringing the mobile browser up to par with Apple's Mobile Safari. The e-mail and SMS applications are also scheduled for complete rewrites. Microsoft plans to make the user interface even more consumer-friendly.
