Today, utilizing a personal computer in your small business has become more than a necessity. Even a tiny kiosk has its billing system computerized. So we cannot run away from this reality so easily; we may have to invest in a quality computer sooner rather than later. When we decide to buy a computer the first question that pops up is the confusion about whether to purchase a laptop or a desktop PC
The type of computer you choose will depend on how you intend to use it. If your school allows notebook computers in the classroom or has a wireless Internet, then you should probably buy a notebook computer.
If your school doesn't allow computers in the classroom and you have no real need for wireless Internet, then you would probably be better off with a desktop. Also if you are a computer gamer,graphics designer, artist, photographer, or have other computing needs that require a faster computer, then a desktop is your best choice.
