Hackers go after the big targets. PCs get hacked way more than Macs because there are so many more of them. Glory comes from bringing down tons of people, websites whatever.
The hacking of Apple/Macs is on the rise as they become more popular. NYSB is built on WordPress which is currently thought to be the best blogging platform - 30% of all websites in the US were built on WP last year (far more than any other) - and the hacking of WP is on the rise.
Apple products also have structural advantages that make them less vulnerable. But not immune.
