While the completion of the Pierre Auger Observatory (or simply ``Auger'') is
still underway, the 5165 km^2.sr.yr integrated acceptance accumulated since the
January 1st, 2004 is now significantly larger than what was gathered by the
previous experiments dedicated to the detection of ultra-high-energy cosmic
rays (UHECRs). We report on the development status of Auger and present some
results related to the cosmic-ray energy spectrum, composition and
anisotropies, and the photon fraction at ultra-high energy. We briefly discuss
the importance of the ankle region to understand the overall phenomenology of
cosmic-rays, and mention future enhancements of Auger focusing on this energy
range.Comment: 10 pages, 10 figures, Invited talk at the International Symposium on
