Why make things difficult when they can be easy? Kill two birds with one stone by buying a keyboard with mouse. This way, you're ready to start working with your laptop or computer in one go. On top of that, it's cheaper to buy a set instead of buying the 2 accessories separately. There are sets for gamers with shiny RGB lighting. There are also home office sets with ergonomic keyboards and mouses. Choose a wireless keyboard and mouse for more freedom of movement. You only need one USB dongle to connect the keyboard and mouse to your PC or Mac. Or go for wired models via USB, so you don't have to charge your keyboard and mouse.
