I want to bring my iBook to school to take notes on it for second semester. However, I've run into a few problems I need to fix before I can. 1. I think I type too loud. My friend, who brings his, said his laptop has something like quiet keys, does Mac have this? I don't want to bug any of my teachers more than I already do. 2. My parents are worried it will get stolen, what can I get to reassure them it won't. I'm 99% sure it won't, it will be on me the whole time, but what can I do if it does get stolen, is there any way to track/find it as reassurance for them? 3. What is a good program to take notes on? Something quick that I can easily organize later. Preferably free.
