I am the odd one out in my circle of friends in that I own an iBook. They all are fairly hardcore PC people (we are all studying electrical engineering) and I can't seem to convince them of the mac's superiority. I have shown them the G5 information and it's impressive gate length, etc and they are still unimpressed. Unfortunately I can't offer any real data on its performance since its not released yet. Most of my friends are of the mindset that OSX is for artists only and not engineers. I say why generalize, it's for anyone who enjoys computers. I don't really care waht they think - I am not going to stop using my mac on their behalf. I just am tired of having to defend my mac and why I use it. What tactics have you guys found most helpful in convincing your friends to give the mac a little respect?
