This is a list of Pocket PC devices, and companies that make, or have made, them. (See also List of Windows Mobile devices.)
Only the Casio E-115, E-125 and EM-500 were Pocket PCs. All others were using the older "Palm-sized PC" operating system except for the BE-300, which ran a stripped down version of Windows CE 3.0 and would not run any Pocket PC software and many applications written for Windows CE itself.

Note that the 600, 700 and 800 series were Handheld PCs that came before the Pocket PC platform was launched.
None of the Philips devices were Pocket PCs. The Nino was a Palm-Sized PC that preceded the Pocket PC platform and the Velo was the older still Handheld PC platform.
Vadem devices were not Pocket PCs but were the older Handheld PC platform.
