 Pocket PCs and personal digital assistants were originally the intended platform for Windows Mobile . These were grouped into two main categories : devices that lacked mobile phone capabilities , and those that included it . Beginning with version 6 devices with this functionality ran " Windows Mobile 6 Professional " and those that lacked it ran " Windows Mobile 6 Classic " . Microsoft had described these devices as " a handheld device that enables you to store and retrieve e @-@ mail , contacts , appointments , play multimedia files , games , exchange text messages with MSN Messenger , browse the Web , and more " . From a technical standpoint Microsoft also specified various hardware and software requirements such as the inclusion of a touchscreen and a directional pad or touchpad .
