From a technical standpoint, "Pocket PC" is a Microsoft specification that sets various hardware and software requirements for mobile devices bearing the "Pocket PC" label.

For instance, any device which is to be classified as a Pocket PC must:

• Run Microsoft's Windows Mobile, PocketPC edition
• Come bundled with a specific suite of applications in ROM

Note: the name Windows Mobile includes both the Windows CE operating system and a suite of basic applications along with a specified user interface

• Include a touchscreen
• Include a directional pad or touchpad
• Include a set of hardware application buttons
• Be based on an ARM version 4 compatible CPU, Intel XScale CPU, MIPS CPU or SH3 CPU. (As of the Pocket PC 2002 specification, ARM-based CPUs are required.)
