Cisco Live is obviously the biggest networking event of the year, and Cisco likes to use all the attention to show off some of their new gear.  I must say I was impressed with some of the Enterprise offerings including the 6807-XL, the 6880-X, the 4451-X, and the Sup 8-E for the 4500-E (check out the Nexus 7700, too, even though they aren’t Enterprise class).  Those boxes definitely gave me a bit of a tingle when I was checking them out, but my eyes opened up when I saw the 3850 in one of my sessions and on the show floor.
