So not the display nor the keyboard, the parts that most commonly need to be replaced.
DIMMs and SSD slots are already standard aside from Apple machines and WWAN functionality has damn near always been a slotted card. All Lenovo did was make the battery easy to replace, really. That got them a 9.3 out of 10?
I'm going to take a wild guess that iFixit got a contract for parts or something in exchange for stroking Lenovo's, uh, Trackpoint?
