What is the difference between Windows CE and Windows Mobile

Aside from syntax, the main difference is that C# is managed and C++ isn't(unless you're using managed c++?)

They're both OO languages(not C). C++ allows you to do your own memory management(which could be a good or bad) while C# is managed code so garbage collection is mostly done for you by the runtime. If you use C#, you will be able to access all other managed assemblies targeted toward the CLR.

No big difference between them, you can Target Windows CE from VS and your application will work on both Windows CE and Windows Mobile. because you are working under Compact Framework so that's logical, for me as a developer working on PDAs, just I find deference when I tried to make full screen program.
