Bounds on the Higgs Boson Mass from M_W

Recent experimental and theoretical progress in the M_H estimates from M_W and Sin^2_eff_lept is reviewed, with particular emphasis on the role played by M_t. Assuming that the SM is correct and taking into account the lower bound on M_H from direct searches, we derive restrictive bounds on M_W and M_t. We also discuss a representative ``benchmark'' scenario for the possible future evolution of these parameters. Amusingly, this benchmark scenario suggested some time ago a value for M_t that turned out to be in very close agreement with its most recent experimental determination.
