There has been some recent discussion on full frame sensors vs smaller sensors (crop bodies). Ken Rockwell recently wrote up an informative comparison between the two: http://www.kenrockwell.com/tech/full-frame-advantage.htm.
Bottom line: For the equivalent picture, larger sensors give sharper pictures and lower noise at high ISOs because the sensor pixels are bigger. (There is more detailed info on noise at http://www.clarkvision.com/imagedetail/does.pixel.size.matter/index.html.)
Also, the larger sensor camera will have a shorter depth of focus, all else being equal. The depth of focus will be the same if the lens aperture diameters (=FL/F_stop) are the same. There is a nice analysis at http://www.clarkvision.com/photoinfo/dof_myth/index.html.
