There are many disadvantages to Laptops too. Like they are very compact and so some of the latest technology that gets developed for desktops cannot be made into thinner and smaller forms. So these technologies cannot be fitted into laptops very successfully. This makes laptops a little behind desktops in terms of capability and efficiency.
