One remarkable reality of the personal computer revolution is that the computers and the components in them continually get faster, smaller, and cheaper. One dilemma this has led to, for many buyers, is deciding just what type of computer to buy when it's time to replace your current one.
The major decision is between a traditional "desktop" computer, which sits atop a desk in your office or home, and a "laptop" computer, also called a "notebook" computer, which can perch on your lap and is not much bigger than a notebook you might tote around with you on the way to a meeting or class. The term "laptop" used to refer to a larger portable computer and "notebook" to a smaller one, but this distinction has largely disappeared.
To complicate matters even further (whoever said computers were easy?), you can choose among different types of both desktop and laptop computers.
With desktop units, big tower PCs are more expandable than mid-tower systems, and this can be helpful for advanced users. Compact systems and all-in-one units are less-expandable still. The latter units integrate the monitor and case and are very easy to set up.
With laptops, "desktop replacements" pack virtually all of the computing power of a desktop system but can still be conveniently transported from one location to another. Ultraportables are for "road warriors" who travel frequently with their machines and can benefit from having to lug around the lightest burden possible. Value notebooks offer a middle ground between the two at lower prices.
One sea change in the world of computers is the increasing feasibility, even desirability, of using any kind of laptop as your sole computing device, whether in the office or home or away from it. Unlike in the past, today's laptops provide all the processing power, memory, and hard disk storage space that most users need at a price premium that's the smallest it has ever been. And the market has responded. And thats all for me i choose laptop because its small.
