The XDA Exec runs Windows Mobile 5, an updated version of Microsoft's handheld operating system. Many of the changes from the previous version are under the hood, with the general look and feel remaining familiar. Notable changes include some enhancements to the built-in software Word Mobile and Excel Mobile (renamed from Pocket Word and Pocket Excel), the introduction of a PowerPoint viewer and two new soft-menu buttons on the touch-sensitive screen whose roles change depending on what application you are using at the time.
