say well with a mac you can't upgrade it? Some of my more technical knowledgeable know about the powermac or in the future mac pro they like it but think it is so expensive. They tell me I can build my own computer for less than a $1,000. I have a hard time responding back, I would say this would be the number one grudge against the Mac. Not only from friends but people I meet day in and day out. How would you fight back with this misconception? Hope someone can help. Thanks.
