• Laptops and PDAs are becoming increasingly popular due to reduced costs, lighter weights, increased capabilities, and battery power for portability.PDAs and Smartphones are small, handheld devices with many of the capabilities of a computer, such as an address book, calendar, e-mail, and Internet access.Laptops and desktops have ports that are virtually the same; therefore, the peripherals are interchangeable.

• Laptops can use docking stations or port replicators to quickly connect to desktop peripherals and AC power.Desktop and laptop components, such as motherboards, are not interchangeable. Additionally, laptop components tend to be proprietary to each manufacturer and designed with unique form factors.The laptop CPU is designed to use less power and create less heat than the desktop computer.
