Actually, I find it useful. Sometimes I want to have the cpu graph while I'm working (always on top) but the entire window takes up way too much space. Solution? Dbl-click the task manager and make it about the size of three horizontally aligned postage stamps, then move it out of the way.

Sure, there are third party utilities that can do that but this is built in.
