Gotta love that they know how people tinker with their devices:

Rear cover screws now thread into metal

Adjusted rear cover screw heads to Torx™, as well as other materials and geometry tweaks on the heads to reduce stripping risk

Lowered number of screw types throughout system

Reduced step count required for common repairs

Improved bumper switch mechanism drop reliability

Moved bumper switch to joystick board for easier repair

Improved display repair/replacement to not require taking rear cover off
