People also object to ergonomic vertical mouses. By design, they cannot be used by everyone. For example, if a computer is intended to be shared by the public and its mouse is a right-handed vertical mouse, installing an ergonomic mouse may discriminate against left-handed people. I don’t necessarily have a good solution to this, as most vertical mouses offer separate right- and left-handed versions. It may just not be feasible to use a vertical mouse in this type of environment.
On the other hand, if you spend most of your time at your own workstation or are ambidextrous, the above may not be a problem for you. The great thing about a vertical mouse is that it is easy to learn, moderately inexpensive, and eliminates a lot of discomfort. For almost all computer users, I would recommend looking into non-standard mouses, especially vertical mouses that use your larger muscle groups and appendages to operate.
A general objection to all non-standard devices is that if you travel, you cannot bring your setup with you. For individuals who rarely travel, this is not a significant objection. However, if you are like me, you spend a significant amount of time (10 to 20 percent) away from your setup. You may need to use your computer on the train, on an airplane, in a hotel room, or in a remote office. You can bring some of your equipment with you, such as your keyboard, mouse, and foot pedal. It is unlikely, however, that you will have a good chair or a second monitor with you. You can try to minimize the amount of work in a suboptimal environment, create a makeshift setup, or buy additional equipment for a remote office.
