I usually never get extended warranties for my PC, as replacing parts is relatively inexpensive. I consider my Imac an investment, and would like to utilize it for a long period of time, (3-4) years depending. I have a few days before my one-year apple warranty expires and I was wondering if it's a good idea to extend it before my chance expires? I assume once the warranty is over, fixing a unibody mac would become expensive from service repairs, diagnosis and replacements.
