  After an introduction on the peculiarities of flavor-physics measurements at
a hadron collider, and on the upgraded Collider Detector at Fermilab (CDF II),
I show recent results on two-body B0 and B0s decays into charged,
pseudo-scalar, charmless mesons or into muons, to illustrate how the flavor
physics program at CDF is competitive with (in B0 decays) and complementary (in
B0s decays) to B-factories. Results shown include the new measurement of the
CP-violating asymmetry in B0-->K+pi- decays, the first measurement of the
time-evolution of B0s-->K+K- decays, and the world best limits on the decay
rates of rare B0/B0s-->mu+mu- modes.
