“Do you have to use a keyboard like this with the Surface? I just bought the Surface yesterday online here but didn't get keyboard yet. Do you have to have a keyboard to use the surface or can you just type in on the tablet on the touch screen? Are these the only keyboards that work with the Surface? I picked up a keyboard/w cover today that is blue tooth driven and wondered if I can use it since with the Surface? It says it works with iPad but didn't say anything about Surface but if the Surface has Bluetooth will it work. Does Surface have Bluetooth?”
