Confirmation Bias plays a huge role. It is VERY difficult for the brain to break past what seems to be a societal norm, at least in the modern tech scene. Also, when it's seen as the way to "get things done" programming-wise, then many of the coolest new toys and utilities will first target the mac. Take Ruby on Rails -- only now, years later, is doing rails development on a Windows machine in the realm of possibility (but still not recommended, personally). VMs can lower the bar, but trying to program inside a VM can be quite frustrating. Plus, add in a dash of consumerism and the modern psychosis of increased perception of value with rising cost, and you get there. It's not a huge leap; put an MBP and a Toshiba side-by-side, and which looks nicer?
