Ergonomic concerns don't stop when you shut off your PC. Even carrying your notebook the wrong way can eventually cause back and neck problems. That's one reason we're impressed with Targus's many backpack models designed for carrying computers.

One is the student-friendly Targus Matrix Notebook Backpack, which holds systems with 15-inch displays, offers contoured mesh shoulder straps, and even includes a removable mobile-phone case.

The Targus Noteworthy Expedition Backpack protects your notebook with air cushioning. It includes pockets for business cards, file folders, and power cords. It also provides foam pads that reconcile the hard, flat surface of a computer with the smooth curves of your back.
