TDD as in religion is overrated. TDD done right is IMHO extremely effective.

The problem is, writing good tests is really hard, and I have seen/committed/experienced a lot of bad tests... just the top of my mind problems with TDD done wrong:

testing the implementation instead the interface
creating a change detector
not writing / factoring the tests in a good way
writing tests / TDD w/o having an overall design for the software

For every non trivial piece of software written w/o TDD, I always saw the same pattern: First few hours/days/weeks, rapid progress compared to TDD, afterwards: hours/days/weeks wasted in debugging, bug fixing etc... and the people can not even catch up with tests if they wanted.

Is TDD always the answer? Of course not, it is a tradeoff like everything else in technology. OTOH I have yet to see a project which benefited from not using TDD by any metric after a few days in.
