Time for us to do what we do best: jam tools into things and see what comes apart.

Let's start with some keycaps. Remember the iMac's Magic Keyboard? It's a well-liked, reliable design that Apple calls the "core technology" for the redesigned keyboard in this new machine.

That might be understating it slightly: side by side, we're hard pressed to spot any differences. Scissor switches, keycaps... There's slightly less space surrounding these new keys, and pundits will celebrate those reconfigured arrow keys—but everything else looks nigh identical.

To round out the comparison, here's a third image showing the controversial (and notoriously temperamental) "butterfly" switch in the 15" MacBook Pro released just a few months ago.

But why stop there? Here's a shot of the scissor switch in the "unibody" 2012 MacBook Pro design...
