MEIZU M8 English review.

There's nothing that prevents capacitive technology from being used in a Windows Mobile device. I think that some where along the fact that Windows Mobile OEMs don't use capacitive screens was mistated as the OS cannot use capacitive screens.

Here are a few related considerations:

Microsoft does not ship a build of the Operating System to the OEMs. Microsoft ships what is called the Adaptation Kit (or the Adapation Kit Updates, or AKUs as they are called). When an OEM receives an AKU that OEM then selects which components of Windows Mobile will be included in their build, which components will not be included, and most importantly of all the OEM must provide their own drivers for the hardware. If an OEM wanted to make a device with a capacitive screen they can do so as long as they provide an appropriate drive so that the touch interactions can be communicated to the operating system.

In the case of Windows CE instead of the Adaptation Kit one has the Platform Builder. If I wanted to create a product using Windows CE I would either purchase a Windows CE development board which will come with the Platform Builder and an appropriate Board Support Package (the Board Support Package (BSP) contains the collection of drivers required to work with a particular OEMs hardware) or if I were the OEM I would need to make my own BSP. Drivers for some common pointing devices are available for Windows CE (example, USB Mouse). But an OEM or individual can use any type of pointing device provided that an appropriate driver is made available for it.

If I wanted to track eye movement and blinks and use those as pointing device input I can do that as long as I can provide a driver for it the OS can handle it. The OS doesn't provide support for simultanious points being pressed/clicked so the limitation present within the OSes prevents [intrinsic] support of multitouch. But that doesn't prevent a capacitive screens from being used.

As for the reasons for the different versions of CE it is to allow for specialization of Windows CE for different purposes. After the Windows Embeded Team makes a new version of CE the Windows Mobile team will take the pieces of it that are to be included in Windows Mobile, add the components that are specific to Windows Mobile, and eventually make the results of their work is released through the AKU. There's also the automotive edition of the Windows embeded OSes that has other services that are not necessarily included in Windows Mobile or the base Windows CE versions. A negative side affect of this is that Windows Mobile is never based on the latest version of Windows CE. The currently available version of Windows Mobile is based off of one of the Windows 5 versions and thus doesn't inherit from the new features that Windows CE 6 supports.

On another subject it's interesting to note all of the different classes of devices that run Windows CE. The Sling Media box and a few GPS navigators are based on Windows CE. There are also robots, printers, displays, ATMs and other devices that run Windows CE.
