--- I got into virtualization with an early beta of the workstation product and got my first license as a student - taking some graduate level "electives" - at a Linux Users Group in Atlanta, GA. Have had my share of good and bad across the entire VMware line (except the fusion/Mac stuff). Now working as a virtual infrastructure consultant for Solution Oriented LLC in Birmingham, Alabama.
