I'm So Stupid...

Or should I say "technically retarded"? Of course this doesn't apply to, um, like, everything but in this case that's really the case: technically retarded.

I've got two Apple laptops, one for work, and one for "not work". It wasn't until recently that I realized that you can do this with the cord. It all makes sense, now. And I don't have to fold the cord in knots to make sure it sticks to the charger when traveling, not any more.
Did you know this?
