One of the first steps in the process is to determine what you want to use the computer for. Both have their own benefits and advantages. Laptops One of the largest benefits to a laptop is the ability to take it anywhere. That means you could take it to class for note taking purposes. Or pick up and take it to the library to avoid a noisy roommate or hallway.
Size is another benefit.
