I haven't experimented much with the delayed start option yet... where does the time go!
For obvious reasons, I would NOT recommend adding your anti-virus, firewall, or protection programs to the delayed start unless you regularly start up and use your computer offine... and I mean physically disconnected from the internet.
Perhaps programs such as MS Office, Messenger, i-Tunes, QuickTime, and MS LifeCam could be worth considering. I suggest looking at what programs are starting with your computer (right-click on Scotty and select Display Startup Info), deciding which of those programs you don't immediately need, then add them to the delay function. Add them one-by-one so you can check that you don't get any problems. You may also want to stagger the delay time so that they don't all start up at the same time.
Hope that helps
