Hadnt noted the higher input lag, that would put me off (though guess it would give me an excuse the next time my god-son kicks my ar$e on Halo!).
It's not mentioned in the Cnet review; though David Mackenzie flagged this up as the ST60's Achilles' heel:

Scroll down to the Console Gaming section for lag readings.
As for your Halo performance, input lag is a terrible excuse! Your son would be no less hampered. Besides, aren't you one of those nice dads that lets their son win?
