Like the iPhone and ipod itouch, the iPad's glass touchscreen may be the main way you contact the device. Each time you surf the Web or send some email, your fingers tap, slide, and flick across this smooth surface. Do that sort of thing on a normal piece of glass and you end up with a smudged and sticky window or mirror, gunked up from finger grease, moisturizer, and whatever else you may have on your hands.
Thanks to a special coating, the iPad's screen attempts to repel fingerprints. However with enough use, even that has its limits; your screen starts to look like a small child who's eating a glazed doughnut has been touching your iPad repeatedly - with both hands.
If this happens, wipe the screen gently having a soft, lint-free cloth - the type you use to clean a flat-panel TV screen, camera lens, or set of glasses.
Whatever you do, don't use products like Windex, Formula 409, stuff from spray cans, ammonia- or alcohol-based cleansers, solvents, or a scratchy cleaning pad. These kinds of cleaning products is only going to compromise the iPad's special coating, and also you don't want that.
If the remaining iPad gets schmutzed up, a quick cleaning session can return its shine. To buff it up, turn it off and unplug it from any connected docks or USB cables. Then have a lightly water-dampened lint-free cloth and wipe down the iPad's back and sides. Be careful not to slop water into openings such as the headphone jack, Dock Connector port, or speaker grills. Then wipe your slab down having a dry lint-free cloth.
The iPad screen is scratch-resistant, bit it might break if you accidentally bounce the tablet off a concrete floor or have some other gravity-related mishap. If disaster strikes and also you crack or chip the screen, don't use the iPad or attempt to pry out the broken glass. Put it in a box or wrap it up to prevent glass shards from falling out, then take it to your nearest Apple Store or authorized Apple service provider for repair.
To protect your iPad as much as possible, both from accidental drops or even bouncing around in your shoulder bag alongside house keys, sunglass cases, and loose credit cards, consider a case for it.
Accessory makers have already come up with a huge selection of cases, from stately leather portfolio models to neon-colored rubber shells meant to jazz up your iPad while helping you keep a firm grip on the thing.
When considering a case, think about how you plan to carry and use the iPad. If it's going to ride along in a backpack, a sturdy padded pouch may be more protective that a thin leather binder-type cover.
