I give an overview of accretion disk spectral states, including a discussion of in which states these jets are seen. I highlight the differences between neutron stars and black holes, which may help give us insights about when and how the presence of a solid surface may help or inhibit jet production.10 pages, 1 figure, invited review at the "RS Ophiuchi (2006)" conference, to appear in the ASP Conference Series edition for the conferenceAstrophysicstext
