Tablets are also useful for watching video in cases where a large TV is impractical or just plain unnecessary. They typically have longer battery life than laptops, which makes them extremely useful on long haul flights, and easier to pull out of a coat pocket than a laptop. They're also typically cheaper; I don't mind using a £100 tablet on a train to check emails or whatever, but I'm more leery at pulling out a £1200 laptop.
