There are many advantages of using a laser keyboard over a traditional keyboard. One advantage is that you can use it on any surface, including glass and metal. This means that you don't have to carry around a mouse or other input device with you when you travel. Another advantage is that laser keyboards are much more durable than traditional keyboards, so they will last longer. Additionally, they are often more comfortable to use because they don't require as much pressure to activate the keys. Finally, some people find that they can type faster on a laser keyboard because the keys are closer together.
