Though laptops are slim and portable, some people prefer a full-size keyboard and monitor, as well as a mouse. Besides being more difficult to steal, desktop computers have an array of advantages over laptop computers. With the innovation of microprocessors, flat-screen monitors and wireless keyboards, desktops have become more compact.
Price
You tend to get more for your money with a desktop computer than a laptop. Even though laptops have decreased in price over the last few years, you still pay for the convenience of portability, sacrificing speed in turn. Laptops cost more for the same internal parts you would get in a desktop computer for considerably less, mainly because laptop parts have to be manufactured to fit in a smaller case.
Upgrades
Because laptops are much smaller, it makes it nearly impossible to upgrade most parts. With a desktop computer, you typically can open the case and install new parts fairly easily. Because laptop mother boards have to be secured to the inside of the case, access is limited and it's difficult to change parts. Laptops usually allow you to change a hard drive, or memory compatible with your motherboard, but you are bound by the original motherboard.
Ports
Laptops have a limited number of ports, restricting the number of plug-in devices. Most laptops come with a set number of USB ports, headphone jack and a microphone jack, but anything else may or may not be included. With a desktop, you can easily enough buy a new video or audio card with additional ports that you need. You can also add more USB ports and other hardware as long as they're compatible with your motherboard.
Faulty Parts
With a desktop it is fairly easy to fix a problem when a part no longer works correctly, but with a laptop you often can't do a thing unless it's still under warranty and you are entitled to a replacement. Desktops allow you to troubleshoot and replace faulty parts. If a power supply fails, you can replace it rather than having to buy a new computer.
