Two apps that I use frequently is the CA Unicenter Service Desk and Igoogle. The CA Unicenter Service Desk, "delivers high-quality, consistent IT service support with CA Service Desk Manager that can automate incident, problem, knowledge management, interactive online support, self-service and advanced root cause analysis"(http://www.ca.com/us/service-desk.aspx) I use this on a daily basis for my job. It is used to track incidents or "tickets" when people call the Help Desk. Also, IGoogle, which includes all of the Google applications is a great thing. I have my little dashboard with all of my favorite apps right there.
