Random usability rant: I find it slightly odd that, even now on Windows 8, keyboard customization requires so much effort in Windows. For example, I always make my capslock key an extra control key (if you haven't tried this before - try it!) and on OS X and most flavors of Linux, this is an easy 5 second process.

On Windows 8, there are a ton of Keyboard settings - including promising-sounding ones like "Change how the keyboard works" and "Keyboard properties" - yet you still have to use a stupid registry hack to actually change the behavior of keys (ie, to make your capslock key an additional control key).
