In general by design:
- Wire Device: Stationary, aren't going move from where it plug in. Limited by the length of the wire.
- Wireless Device: Portable, able to be flexible in placement and uses within the range of the receiver of the device one is using.
Wire Keyboard & Mouse:
Pro:
- Always connected/powered (never loses connection to the PC)
- limited to the length of the wire and how far you can move it around the pc area.
- cluster/cumbersome if you are or your area around your PC is unorganized due to limited space
Wireless Keyboard & Mouse:
Pro:
- portability and flexibility to move the device anywhere within the range of the receiver.
- less cumbersome to those with limited space or unorganized place to places the keyboard & mouse on
- battery. How long a battery last depend on what you doing on the PC (main purpose on the PC), brand of the Keyboard & Mouse, and what kind of battery. Think of the wireless keyboard & mouse battery as gasoline for your car or the ink for the printer. They are like that kind of thing.
- currently there two type of battery that wireless keyboard & mouse uses. The common "AA" battery or the internal rechargeable battery within wireless keyboard & mouse.
- "AA" battery can one time uses or the rechargeable "AA" battery.
- internal rechargeable battery something similar like your cellphone or tablet. (*personally I never use this type or heard of this before but it something new for me. However I can see the limit of this kind of battery over the "AA" battery and other issue if push too hard or recharge too much since I done that to my other device that I recharge a lot. Main issue: you can't change the battery if you kill the battery.)
- connection; since you are not physically connect to the PC depending on the device (brand), how much and how hard you uses it, and the PC itself. You might lose connection if the device or the PC die on you.
