Get the AppleCare! You will be thankful you did, if anything ever happens in the span of 3 years from your date of purchase. Better safe than sorry.
In the case of your school not having any problems with their 40 MACs...well, they might just be fortunate to have no problems, but doubtful none of the machines ever had problems. They probably had a outside tecnician service their Macs...you just don't know about it.
In my case, I've been on both sides of the fence...Not having AppleCare and Having Applecare. The one-time I didn't have AppleCare, I paid like $400 for screen repair on my iBook, since then I sold it and bought a Powerbook w/ Applecare. My point is whenever you purchase something expensive as computers, its in your best interest to get some sort of warranty. In this case AppleCare is great to have...it's already paid for itself with my Powerbook Ti.
Case in point: I just sent my Powerbook in for servicing because I was getting horizontal lines on my screen. Then, the MAC genius discovered that there was something wrong with my harddrive. So, I'm getting practically the whole laptop serivced free under my AppleCare, which is about to expire in a few months. I'm guessing if I decided to fis it outside AppleCare it would run me $1K to fix, which is not worth it. Anyhow, I'm hoping they can't fix it and they offer to give me a Aluminum Powerbook that's comparable to my Titanium version. Hehehe!!! Wishful thinking but you never know.
Get the AppleCare! I bought it for my new iMac.
