In the past, we used to have to purchase expensive PC monitors and keyboards to use our smartphones as remote desktop PCs. But these days, we can do much more with our mobile devices, which makes us wonder why we have to use a PC in the first place. The answer is simple: A PC is a convenient way to display and interact with your smartphone or tablet. You can drag and drop files, type text messages on your keyboard, and much more. You can also use the built-in microphone to make a video call to someone else or use the built-in camera to take a photo and share it with your friends. But now, there is a new, even better way to use your smartphone or tablet as a PC: SideSync.
