They are big, they are loud, the take up a lot of space and they are not portable. Desktop computers were the norm in the early days of computing however, now that laptops have become much more powerful and much more affordable, I believe that desktops are no longer necessary. Why would anyone want to have a computer that just sits and keeps all your data but, can’t go with to work or on a vacation. Although desktops can get better specs for gaming and processor speed but, for the vast majority of users notebooks are more useful because it does not require the purchase of an additional monitor and can take all your data with you anywhere you go. For the past four years, my primary computer has been a notebook and there is nothing my notebooks can’t do that I need.  I recommend people considering buying a desktop to think again before buying that because it could be much more convenient to get a notebook.
