It does say moderate difficulty, however in all honesty it's pretty easy if you know how to go slow, keep track of screws, and not force anything. Of course, helps to have experience inside the MacBook to know your way around, too, but I'd say that's probably not necessary :)

Cleanup itself might be a sticky situation, sewing seeds of doubt wherever you go.

Touchpad is also in the latest MacBook Pro laptops

Perfect mix of comedy and helpfulness!!
