Windows CE is a modular/componentized operating system that serves as the foundation of several classes of devices.Windows CE (also known officially asWindows Embedded Compact or Windows Embedded CE post version 6.0, and sometimes abbreviated WinCE) is an operating system developed by Microsoft for minimalistic computers and embedded systems. Windows CE is a distinct operating system and kernel.
Windows Mobile is best described as a subset of platforms based on a Windows CE underpinning. Currently, Pocket PC (now called Windows Mobile Classic), SmartPhone (Windows Mobile Standard), and PocketPC Phone Edition (Windows Mobile Professional) are the three main platforms under the Windows Mobile umbrella. Each platform utilizes different components of Windows CE, as well as supplemental features and applications suited for their respective devices.
Pocket PC and Windows Mobile is a Microsoft-defined custom platform for general PDA use, and consists of a Microsoft-defined set of minimum profiles (Professional Edition, Premium Edition) of software and hardware that is supported. The rules for manufacturing a Pocket PC device are stricter than those for producing a custom Windows CE-based platform. The defining characteristics of the Pocket PC are thedigitizer as the primary human interface device and its extremely portable size. PocketPC is a separate layer of code on top of the core Windows CE OS. Pocket PC is based on Windows CE, but it's a different offering. And licensees of Pocket PC are forbidden to modify the WinCE part.
"Windows Mobile is not Windows CE (and vice-versa), Windows Mobile has Windows CE as its core – WM 2003 was based on WinCE 4.x, WM 5.0 is based on WinCE version 5, WM 6.1 is based on WinCE version 5.2.* – plus a standard shell, applications and APIs"
