What is "missing" in the Visual Studio 2008 Express Editions?

Solution 1:

The major areas where Visual Studio Express lacks features compared to Visual Studio Professional:

• No add-ins/macros
• Some Win32 tools missing
• No Team Explorer support
• Limited refactoring support
• Debugging is much more limited (particularly problematic for server development is no remote debugging)
• Lack of support for setup projects
• No report creation tools
• No Office development support
• No mobile platform support
• Limited set of designers
• Limited set of database tools
• No code profiling or test framework support
• No MFC/ATL support
• No support for compiling C++ to 64-bit images (workaround is to install Windows SDK which is free)

NOTE: it is often said that the Express EULA does not permit commercial development - that is not true (Visual Studio Express FAQ Item 7)

Solution 2:

There's a handy set of comparison charts on microsoft.com.

It depends on the particular express edition, of course (since there are several and they have different features). The limitations you're most likely to run into are source control integration (and TFS client license), debugging limitations, limited refactorings, no unit testing support, and limited designer support.
