The PEP-II B-Factory has completed over two years of physics running. During this time its luminosity has reached a peak of 4.5 10³³ cm^-2 s^-1, and over 70 fb^-1 have been delivered to the BaBar detector, significantly exceeding the CDR projections. Issues presently limiting luminosity will be discussed, including HOM heating at certain beam-pipe locations and electron-cloud effects. Other studies we undertook include determination of the beam-beam tune shift and the resulting Landau damping by beam-transfer function measurements; optical-function measurement (including for the 90° cells in the LER), and Touschek-lifetime measurements of the positron beam in the LER. The presentation will conclude with a review of possible upgrade scenarios.
