Are you a regular at BootCamp? If the answer is yes, you may have thought sometimes that it would be great if there was a faster way to start Windows.
Well there is, it's called QuickBoot and it allows us to choose the partition we want to load from Mac OS X immediately, so we forget the Alt key when rebooting.
I am more of virtualizing, but If you are from BootCamp you can give it a try.

But that already exists right?
System Preferences -> Boot Disks -> select the one you want and -> Restart ... (the button is with ellipsis included).
