iLEVL is a copy holder especially designed for the iMac — made from a single sheet of steel, it uses the magnets on the right side of the iMac (where the Apple Remote goes) to stay in place. It costs $8.
Useful for secretaries, copy editors and others who need to look at sheets of paper while working, iLEVL features a non-slip protective rubber coating and can be pivoted for an adjustable paper tray angle.
