Separate displays is useful for multi-headed systems.  I know a couple people who buy one, high-power desktop for the whole family and then attach multiple screens and input devices.
If you want to do that, but your GPU can't handle multiple X displays, you can still set it up by using one master X server, and then running multiple, nested X servers, each given a specific region (which may or may not correspond precisely to one or more screens, but that's usually what you'd want).  Attach the IO devices to the nested ones obviously.
