Really, Nik? It does not to me, but I might assign it the next time I teach a course in Banach space theory. @Terry: The answer is yes if E is separable but no in general; e.g. if $E=\ell_\infty$, because $\ell_\infty$ is a Shur space (that is, every weak$^*$ convergent sequence in $\ell_\infty^*$ is weakly convergent).
