The Tab has a 7-inch screen versus the 9.7-inch display on the iPad. That may seem like a small difference, but the numbers are deceptive, because screen sizes are always described using diagonal measurements. In fact, the actual screen real estate on the Tab is less than half of the iPad's. That's a disadvantage, but it allows the overall unit to be much smaller and lighter, and thus more easily used in one hand, something some users will welcome.
