Laptop bags are essential equipment for many students and businesspeople. A laptop can be fragile or tough, depending on the brand. But it should still have some sort of special cushioning to protect it from being jolted about. Some bags resemble hard shell suitcases, and contain foam compartments for the computer, and for accessories. Other laptop bags are designed to resemble a large purse, so that a professional woman need not so very closely resemble her male counterpart. Student laptop bags are frequently backpacks. Student bags need excellent padding to protect the contents from frequent jostling.
