For the three Apple desktops I've owned, I never had Applecare, and never missed it. My PowerBook is approaching it's one year purchase date, and having had the combo drive replaced a few months back, I am seriously considering getting Applecare for it. I am thinking that a laptop needs it more, since it will travel around a bit, and the parts and service are typically more expensive.
Does anyone know if, having bought a Mac via the EDU store, one can later purchase Applecare with the EDU price (as long as it is within the first year)?
