Also from WaterField Designs, the $79 MacBook Air Travel Express ( ; see full review) is, if you will, a Mary Poppins-style MacBook Air case. Despite being not much larger than a laptop sleeve, the Travel Express can hold the 11-inch MacBook Air along with its power adapter, a mouse, a SuperDrive or power-cord extension, a slim magazine or notebook, an iPhone, and some keys and small cables. Rigid-plastic inserts offer a bit of impact protection. The Travel Express works well as a case inside another bag, or a $12 upgrade gives you D-rings and a strap, turning the Express into a simple shoulder bag. Made of padded, black nylon with an “Ultrasuede” interior, the Travel Express sports a decorative strip in your choice of one of WaterField’s six standard colors—black, copper, pearl, flame, green, or pine. The case is also available, for $10 more, for the 13-inch MacBook Air and the 13-inch MacBook Pro.
