So I just completed the MacOS 101 Mac OS X Support Essentials v10.4 training course that I mentioned earlier. It was a three day course covering basic Mac operation and troubleshooting. While a lot of the course was "Duh" material, there was still a lot of useful information in there. I also managed to pick up some hints in other areas, such as deployment, which should help make life easier.

My sister is also buying a 15" Powerbook. I am so very, very jealous. I want one. Of my own (not the crappy old slow one that I get to use at work).
