There are other Apple shareholders in this forum besides cvaldes. And it's interesting to all of us tracking Apple closely even if for no other reason than curiousity. This isn't an "Apple USA Products" rumor site.
The fact that I'm traveling to China next month and debating a possible move there one day makes it interesting as well.
@Dooger:
Gecktotek is correct. There are others here who are shareholders, some of whom even mention it in their signature.
Note that even if you aren't a shareholder, how Apple conducts its business outside of the United States is significant because that international revenue contributes to Apple's coffers. They have 70 billion in cash which can be used for strategic investments in securing components, as well as M&A (Siri, P.A. Semi, Intrinsity, etc.).
Beyond the sheer revenue numbers, there are also partnerships with other companies that may affect domestic operations.
For example, Vodafone is the world's largest mobile phone company (by revenue); they are the official iPhone carrier in many markets around the planet. Well, it just so happens that they are half-owner of Verizon Wireless (the other half is owned by Verizon Communications). It's very probable that the Vodafone partnership helped bring the iPhone to Verizon Wireless.
Regardless of whether or not you're a current shareholder, reading Apple's SEC filings provides helpful insight into how the company is operated. A conscientious investor studies these documents before choosing whether or not to invest in a company.
