You could always use your phone as a keyboard and navigation input device. However, there is a better option. The Display Dock has three USB 2.0 ports, which is more than enough for a standard keyboard and mouse setup.
Go wireless and type in comfort with the Sculpt Ergonomic Desktop keyboard, which also comes with a wireless mouse. Alternately, free up more ports on the Display Dock with a Bluetooth keyboard with built-in trackpad that connects straight to your phone like the All-in-One Media Keyboard, or go fully portable with the Universal Portable keyboard.
