I was Session Chair of "3D IC and Package Design Issues" in 2007. Being a veteran of many DACs, I regarded this duty as an honor. I practiced my 4-minute session-opening talk for a full hour in the prep. room and timed every speaker to the second. I loved the precision and snappy, no-padding-allowed schedule and the super-high quality of the technical papers. Believe me, I enjoyed every minute of it!
