Mac Mini: Lack of USB Slots After Mouse + Keyboard?

I was just taking a look at the Mac Mini and something struck me. Apple's got these two pics up on the Mac Mini webpage.





Notice that in the first picture you see the USB keyboard and mouse going to the back with separate wires and presumably needing separate USB slots. Then in the second picture you can see that there are only 2 USB slots in the back. (As an aside, the pics also seemed to be aligned in different ways, with the top having USB on the left when facing the slotted side and the second having it on the right.)

So... what do you do when you have to use a USB slot for something else, like a digital camera or a printer? Deal without the mouse or without the keyboard? My guess is that that's pretty unlikely, but I'm not coming up with any way around it just by looking at the Mac Mini webpage. Am I missing something here?
