The one place I still use unit tests is around calculation algorithms where you want to push a lot of different data through. You could do it with an integration test, but the test run overhead of say 100 parameterized integration tests is far too high. In these cases the algorithm will still be exercised by an integration test, but the nitty-gritty will be done in a unit test.
