Laptops can do anything that a desktop PC can do.
They’re portable, and often have as many ports as a desktop but you’re paying a premium for a laptop’s mobility, small size, low weight, all-day battery, and specialized heat management. If you don’t need those features, why pay for them?
Besides, laptops also have their limitations:
Limited screen size – Even the biggest laptops max out at 17”, a size that’s barely considered entry-level in the desktop world.
Slower performance – Generally speaking, laptop CPUs and graphics lag behind desktops. In order to save on power, some sacrifices must be made.
One keyboard – Everyone has a keyboard preference, trouble is, laptops only have one keyboard. If you don’t like it, you have to get used to it or buy a different laptop.
Batteries eventually die – Unfortunately nothing lasts forever, including laptop batteries, which eventually need to be replaced.
