I buy everything critical from the manufacturer of the product. It it's an Apple notebook, I buy it from Apple. Another thing, I only buy from Apple.com if it's a computer. I have had way too many problems going to the store. In addition, when I buy iPods or things like that, I buy at Apple.com because I am afraid I will not get the very latest version if I go to anyplace else. There always seems to be something we don't know about that the very latest has that the prior versions don't. And, it always seems that I could get an older version if I don't buy from Apple.com.
I see all of the Apple resellers, and I know there are probably a few really good ones, but I have had bad experiences trying to get a deal... Just not worth it to me. Especially when I am buying an expensive computer or want the latest technology like with an iPod.
I am sure a million people are going to say I am wrong and they all buy from all of the resellers, but I have had a few experiences that have made up my mind... not to buy from resellers.
