Removing sticker residue from a MacBook/laptop

I like putting stickers on my laptops, to make them a little more personal. But I hate removing the inevitable sticker residue after peeling off stickers before I sell or pass on my old laptop.

In this video, I'll show you my current best technique for getting residue off most metal and hard plastic surfaces. Let me know if you know of any better ways that won't mar the surface or take hours!
