What's left? We pop some more screws and two shields, and the trackpad lifts free from that floating magnetic top cover.

Barnacled to the trackpad, we find some familiar silicon: an NXP/Freescale MK22FN512 Kinetis MCU and Synaptics S9101B touch controller.

That said, with the trackpad out, a keyboard + top cover replacement could be a reasonable repair. And it's about 1.5 zillion times easier than in any current MacBook Pro.

The final bits in the rear case include the still-modular headphone jack—which you can squeak out from under the main board if you're careful.

Of minor note: the Surface Connect cable harness looks a bit more put together this time, clothed in handsome black tape instead of a rainbow of wire insulation. It's somethin'!
