I'd venture to say the internet doesn't get Apple. Many geeks are just anti anything Apple, and have an irrational hatred for them. Apple have made huge contributions to the internet, such as Webkit, promoting web standards, the iPhone and yes, even the iTunes store - still the biggest internet-based media distribution channel.
Nearly every geek I know has a MBP, and every startup I've worked at uses the same.
I think the OSX/Mac overall experience is the best out there, beating Ubuntu 10.10 and W7. (Reliability, programmer-friendliness, 'normal' programs).
