Something that Windows wins hands down – reinstallation.
OS X ‘safety’ features make it extremely difficult to reinstall if you don’t have the previous owner’s Apple credentials. And there is no more optical media. And making a usb boot drive won’t necessarily work either. There’s even cases where people found themselves completely locked out needing another Mac to reinstall. That is ludicrous if you come from the PC world.
I guess stealing Macs is a bigger problem than stealing PCs.
