It is normal that everybody has one keyboard. If you have a modern design computer, then I advise you to buy a nice keyboard. Because the keyboard is also a part of promoting people's work experience. If you have a keyboard with excellent features, it will help you to do your work easier by using the computer.
There are two main keyboards in the world. One is mechanical keyboard, the other is membrane keyboard. Please according to your requirement buy a suitable keyboard.
If you use keyboard but not high-intensity work, I suggest you buy membrane keyboard. Because it is cheap and will match your requirement. So choosing the membrane keyboard is a not bad choice.
If you want to have typing and gaming good use feeling. I suggest buying a mechanical keyboard. It will not cost too much than membrane keyboard, but give you a better experience. When using mechanical keyboards, are way too different from normal ones because they have physical switches underneath each key. It makes typing easy and quick compared to any other keyboard type on the market. Surely, the typing experience will improve, and a user will enjoy typing long texts. And it is better for gaming than membrane keyboard.
Finally, if your budget is enough, hope you buy mechanical keyboards. Because these will let you use more longer, and giving you an excellent experience. If you are ready to buy a mechanical keyboard, please take a look.
