The two most used computer peripherals we use get the least amount of respect and thought…the mouse and keyboard. In fact, many of us shop for the cheapest possible mouse or keyboard when it comes to replace our existing one.
If you still use a standard, corded mouse, you might want to strongly consider spending $30-40 on a new optical or cordless, optical mouse. The primary difference between an optical and standard (mechanical) mouse is the absence of the little ball in the standard mouse.
Optical mice use a LED (Light Emitting Diode) to stimulate a CMOS sensor (the same surface found in digital cameras). Essentially, optical mice have mini-cameras in them that take up to 1,500 pictures per second to track and move our computer cursor around the screen. This leads to our first advantage over standard mice…NO moving parts. Standard mice can accumulate dust, fuzz, and other contaminates that lead to jumpy cursors.
Optical mice also offer these advantages over standard mouse:
* More accurate
* No need to use special surface like a mouse pad.
* Can run on almost any surface except glass.
Add the cordless feature to an optical mouse and you have a great little tool to use with your computer…although you will need to keep an eye on battery strength every 3-4 months or so.
One other type of mouse I feel would benefit many computer users is the track ball. A track ball is basically an upside down mouse. Instead of having to move a mouse around your desk or pad, the unit sits in one place and you roll a ball around to control the cursor.
Trackballs are great for computer users who have trouble holding a mouse still or need more accuracy with clicking on icons or selecting text. A trackball allows the user to first move the cursor to the desired location, take the hand off the ball and click separately.
