Why does Gmail through palm pre (either the Email program, or through the WebOS Browser - both Google Mobile and Desktop versions) not support Create an Event from individual email messages. It's especially strange that the buttons in Gmail through the browser look completely different (even if you don't access it through Google Mobile)...so clearly there's something about the webkit based browser that does not support all of the Google features?

This should be fixed...if you're going to provide access to Gmail - you need to provide full access to all of its features.
