I can't disagree more. When I was working as a technician, I always hated doing iBooks, because it involves about 40 tiny screws, which have to removed and replaced in a very specific order. I don't recommend doing it yourself.
Indeed, the Wallstreet, Lombard, and Pismo G3s, along with TiBooks, made HD replacement super-simple. All iBooks and AlBooks share the nightmarish disassembly.
