Finding the Right Windows XP Desktop or All-in-One

Choosing a PC that runs the Windows XP operating system requires that you consider exactly what you want in a home or business computer. This could mean selecting a traditional desktop model with plenty of media-friendly features or a convenient all-in-one with a slim profile that fits neatly onto your desk at work.

How Does an All-in-One Compare to a Regular Desktop?

There are many different form factors when you're selecting a Windows computer. You've got smaller, portable computers like laptops and notebooks or more traditional machines with towers. Yet another type of computer is an all-in-one, and there are some features that may make it appealing, especially for those users with smaller spaces.

• A traditional Windows desktop has several components that include a monitor, a keyboard and mouse, and the tower that houses the processor, disc drive, hard drive, and other important components.
• Conversely, an all-in-one manages to consolidate all these components into the monitor, or display, meaning you don't need a tower at all.
• The only components you have with an all-in-one are the display and any peripherals you install, such as a keyboard, mouse, or an external hard drive.
