(as I type away on my Mac-mini) I would be UTTERLY LIVID if a Windows update horked my grub bootloader, Apple deserves no less rage for this shenanigan. Can you imagine if a Windows update made your computer unable to boot if you had it set up to dual-boot into Linux? Why do people rush to the defense of Apple when they completely f-BEEP-k up and make a mockery of their cheesy 'it just works' phrase?
