It does - packet-sampled control of flow creation (i.e., true sampled  
NetFlow), logical OR of TCP flags within a flow, dropped traffic,  
layer-2 NetFlow across ports within the same VLAN, larger NetFlow  
table size, etc.

ACL construction is much easier than on 6500 (doesn't have the weird  
LOU constraints), and you get per-interface uRPF mode settings, as  
well (vs. whole-box on 6500).

Sorry, sometimes I mistake your existential crises for technical
insights.
