I think that Apple users have a much more intimate and tangible relationship with the company that provides for their computing needs. When you're a PC user, you might be building your own comptuer -- picking up odds and ends from various companies that really mean nothing to you. You do the same with software -- some of it works well with your hardware, some of it doesn't. The relationship just isn't on the same level as it is with Apple user and Apple the company.
We like the products that Apple makes. We appreciate the work and effort that goes into creating Apple hardware and software. We have some level of respect for the company and the way that they have treated us over the years -- I know that I have had nothing but memorable customer service at the hands of Apple. And, I think we recognize the need for this company to be a successful business. So, when Apple comes out with a new iLife suite and markets it for $89, we feel okay about giving that money to Apple.
I also think that for the majority of Apple users, similar relationships exist for companies like Adobe and for music artists that we appreciate and respect.
I'm not saying that I don't pirate because that would be a lie. I would say though that I have a conversation with myself from time to time to determine whether I'm okay with pirating something.
That's my take on it.
