10.1.1. Straight keyboards have many advantages when you are wanting to input information in to the computer. Some have number key pads to the right of the letter keys to make it easier for those who use numbers frequently. There have recently been some keyboards that are designed for comfort such as the one above. Here is another called SafeType keyboard that is orthopedically neutral correct

11. Mice: there are several types of mice that are available. They do have some that are one click and left right click for

I could add a microphone to it on the side though. Does not enable vision.
