Instead of balancing a keyboard on one knee and a touchpad on the other, a small Bluetooth keyboard is a better option. These ultra-compact keyboards have physical keys and resemble a smartphone turned on its side. They have the same key layout as a full-sized keyboard, plus a small touchpad for controlling the mouse cursor on your computer.
These mini keyboards don’t require a USB dongle to connect to your computer, tablet, or smartphone because they connect via Bluetooth. Their touchpad is only compatible with computers, but it can help you reduce the amount of touch typing you do on mobile devices.
