Are there any wireless usb PC keyboards that have some type of mouse pad attached to the bottom/side? I want a wireless keyboard to use when my laptop is connected to my HDTV, and I'm leaning towards a Logitech k400, which has a built in touchpad. However, I would be interested in a regular keyboard and mouse, but only if there is some type of mousepad attached to the keyboard (so I don't have to use a table, or use the mouse on my leg :P) Is there any type of keyboard like that, or is the one with the touchpad built in the better choice?
