This, along with automatically using an external monitor when one is plugged in, is the reason that I switched to the Mac for laptops. As others are saying, it sounds like the suspend/resume feature works well now. I can add that at least on my multi-monitor desktop Ubuntu 10.10 will reliably automatically adjust when I plug in or unplug one of my monitors. I found this out accidentally and it was really a pleasant surprise. Of course, as always with Linux, both these features probably depend on how well your hardware is supported.
