I recently bought from Apple a refurbished 17" iMac (white model) 2 Ghz Core 2 Duo processor, 1 GB of RAM (which I upgraded to 3 GB) and a 160 GB hard drive. It came with Tiger installed, but Apple included a Leopard upgrade disk. It installed without a hitch. I recently got an email from Apple trying to sell me on AppleCare to extend the 90 day warranty to three years. Is this something I need? They want $169 for it, but I can buy the same thing from Amazon for $149. What are your thoughts? Save my money, or get Applecare for my iMac?
