With an 18-inch laptop, you can work on a large screen and see all details. Thanks to the large size, you can work in 2 windows side-by-side and you have enough space to view your games and movies with a lot of detail. You can use the 18-inch laptop at a fixed spot, because due to the large size and weight, it's less easy to take these laptops with you. In addition, a laptop with an 18-inch screen also has a numeric keypad, so it's easier to enter numbers.
