TDD

My team at work is moving to Scrum and other teams are starting to do test-driven development using unit tests and user acceptance tests. I like the UATs, but I'm not sold on unit testing for test-driven development or test-driven development in general.

It seems like writing tests is extra work, gives people a crutch when they write the real code, and might not be effective very often.

I understand how unit tests work and how to write them, but can anyone make the case that it's really a good idea and worth the effort and time?

Also, is there anything that makes TDD especially good for Scrum?
