I use TDD as a tool. I find it quite heavy handed for maintenance of legacy code where I basically know the solution to the task up front. I can either just rely on having enough existing coverage or create one test for my change and fix it all in one step.
The times I actually use TDD are basically limited to really tricky problems I don't know how to solve or break down or when I have a problem with some rough ideas for domain boundaries but I don't quite know where I should draw the lines around things. TDD pulls these out of thin air like magic and they consistently take less time to reach than if I just sit there and think about it for a week by trying different approaches out.
