Sometimes it can save you.

int mid = (low + high) / 2;
int mid = (low + high) >>> 1;

The first one breaks when low + high > 2^31-1, the second one doesn't (only when low + high > 2^32 - 1).

In other news, premature optimization only counts IMO when the change involves non-trivial optimizations.

You guys are absolutely right.
