The parts most expected to fail are easy to remove, and they even have separate modules for each port. Also, is the TouchID button not paired to the motherboard (so why would one want it to be easier to access than the motherboard in a repair scenario)? The only valid criticism he had was their choice not to use a removable flash module like in their other recent models.
