Gains in notebook sales over desktop PCs result primarily from increased functionality (more efficient chips and wireless networking) and price (in the $1000 range for low-end models). While notebook sales are at the expense of desktop PCs, the buying trend toward notebooks does not signal the demise of desktop PCs. Consider the following comparison of features and attributes between the two: 

• Performance: Advantage, desktop PCs. However, notebook processing speed and memory are sufficient for most corporate and home users.

• Keyboard/pointing device: Advantage, desktop PCs. Keyboards for desktop PCs are easier to use. Notebook keyboards are cramped. Given the choice, most people prefer a mouse over a touch pad. A full-size keyboard and mouse require a docking station on most notebooks, an added expense.

• Monitor: Advantage, desktop PCs. Desktop PCs offer a wider range of screen sizes and resolution. The resolution of notebook screens has improved greatly, but in order to be truly portable, notebook screens greater than 15"  will be impractical.

• Peripherals: Advantage, desktop PCs, but nearly a draw. Most peripherals use USB (or FireWire) and any number of peripherals can be attached to a notebook or desktop PC. 

• Docking station: Advantage, desktop PCs. The desktop PC wins hands down—docking station not required for peripherals, monitor, keyboard, or pointing devices.

• Theft/damage/wear and tear: Advantage, desktop PCs. Notebooks are far easier to steal. You're also more likely to drop, spill coffee on....a notebook. Notebooks also suffer travel induced wear and tear.

• Portability: Advantage, notebooks—their reason for being.

• Cost: Per given memory and speed desktop PCs are less expensive than notebooks, generally $150 to $300 dollars for similar functionality. If you want a 15" screen on a notebook add $150. To make a notebook a truly functional desktop PC, add a docking station ($150-$300), keyboard and mouse ($50) and external monitor ($200+).
