Even with IDEs, I find that I grep through source trees fairly often. Sometimes it's because I don't completely trust the IDE to find everything I'm interested in (justifiably; sometimes it doesn't). Sometimes it's because I'm not looking to dive into the code and do serious work on it; I'm just doing a quick drive-by check/lookup for something. Sometimes it's because I'm ssh'd into another machine and I don't have the ability to easily open the sources in an IDE.
