Following up on our earlier articles about the future of Windows Mobile for data collection devices, here is the official Microsoft site for what is now being called Windows Embedded Handheld. This is what used to be called Windows Mobile, and is the version that will be used by handheld devices (as opposed to Windows Phone 7, which will be used in consumer phone handsets). The current version is Windows Mobile 6.5.
Windows CE is being renamed Windows Embedded Compact Edition. Windows CE 7 is in CTP (Community Technology Preview) and will be released soon.
