I don't know what's up with all these laptop adhesive things, but it's kind of silly. I suppose it might be good if you want to keep your aluminum Powerbook nice and clean, but why would you need one for a generic plastic beast?
These come in pastel colors, are reusable—I match mine to my underwear each day so today my laptop is pink—and cost $35 (!!).
