Most people open the same few applications every time they turn on their computers. Even though I go through a wide battery of apps during a typical workday, I generally always launch Firefox, Entourage, and iChat immediately.
If you're a fellow Mac user, there's an ultra-simple way to launch your most used applications at login.
All you need to do is click into Accounts in System Preferences, and then click into Login Items. Use the plus and minus buttons to select and deselect the applications that you want to automatically launch.
