  In this proceeding, we briefly review three recent results. First, we show
that halos formed in simulations with gas cooling are significantly rounder
than halos formed in dissipationless $N$-body simulations. The increase in
principle axis ratios is $\delta (c/a) ~ 0.2 - 0.4$ in the inner halo and
remains significant at large radii. Second, we discuss the CDM substructure
crisis and demonstrate the sensitivity of the crisis to the spectrum of
primordial density fluctuations on small scales. Third, we assess the ability
of experiments like VERITAS and GLAST to detect $\gamma$-rays from neutralino
dark matter annihilation in dark subhalos about the MW.
