Actually, smoove21, those ARE running Windows Mobile. Most of them Windows Mobile 2003, but some of them run 5 or even 6. The term Mobile does not mean phone at all. Its the same Windows Mobile running on an HTC phone that is running on a Dell Axim PDA or HP iPaq. Some of the software I run on my phone (such as mocha FTP, for example) was made for a PDA over WiFI, before PDA-Phone combos where widely available.
This is a bit off topic, but I think you are confused:
Windows CE is a modular operating system that was designed to be adapted for various uses, like solid state terminals, in-dash car entertainment consoles, GPS units, call center extensions, set-top TV boxes and even ended up on Sega's Dreamcast system.
The idea was that a hardware developer could take a standardized OS and throw modules together to easily suit their need. The default CE UI actually resembles Windows 95, with a cascading start menu on the bottom and task bar. (see here:

One of the divisions of the CE team wanted to compete with Palm's popular Pilot PDA, and when the HPCs didn't catch on (think pocket-sized clamshell laptop), they decided it was because no one wants to open up and use their PDA like a laptop on the go.
So, they created an alternative UI designed for portrait orientation displays, threw together some standardized modules for general PDA use, and called it Windows Mobile (actually, originally Pocket PC, but eventually the name was changed in 2003 for marketing the Windows brand).
Those devices are running the same Windows Mobile we are, although perhaps not as recent a version. Many enterprise portable computing devices such as Point-of-sale guns in Target stores or what stewards use to order and pay for drinks on JetBlue, run Windows Mobile. This is mostly instead of some version of CE because it already exists and is ready to go instead of adapting and developing a customized OS.
That is part of why WM will not really die, even if they lose relevance in the consumer market.
I have a few of those barcode scanners in my office, they used to use them for inventory. Some of the older black-and-white display ones run Windows CE with the old UI, and its kind of funny. In some ways, I wish they had kept that. Its really more like using a desktop, and seems more natural. The newer ones run Pocket PC 2003, one or two of them run WM5. I used to take the unused ones and load all my old crap on them... TCPMP, pocket DOOM, etc., just for kicks.
A coworker of mine who didn't want to carry around a large smartphone decided to actually adopt one as his PDA. Kind of silly I think, since its so big, but he wanted it not just for PIM, but also as a laptop replacement for terminal services and configuring routers though serial cables.
Just setting the record straight, here. WM *is* used for more than consumer devices. CE is a whole 'nother story...
