Query: Not for MacBook Pro unibody models

The tabs are meant for use with a laptop screen that has a bezel of some sort around it. The unibody MacBook Pro has no such thing, being completely flat with its border, so the tabs don't work. The privacy offered by the screen is adequate, but I'm holding it on my MacBook Pro with 3M Scotch tape!
