I agree if possible it is a good idea to add tests to legacy code. As part of one of my yearly goals I am trying to write tests for any new non trivial code, but I want to write tests for as much old code as possible too. A lot of code at my company simply isn't testable and needs refactoring before it can be fully tested. But the day will come when it is all at least good enough to test :)
