When buying a big-screen TV, you can go flat or you can go fat. Flat (with a plasma or direct-view LCD screen) means you can hang your TV on the wall, but you'll feel the pinch in the checkout lane. In the fat camp are the rear-projection screens, which offer larger screen sizes, great resolution and more affordable prices. Rear-projection TVs will also be the first to be
digital-cable-ready, eliminating the need for a digital-cable box. And the best news of all-they're not even that fat anymore.
