So I've been wanting to get an external keyboard for my rMBP. The thing holding me back is that it would take up one of the two USB ports. The wired keyboard seems fitting since it as two more ports (as well as the number pad), however, the ports on the side are USB 2.0, and naturally, I wouldn't want to sacrifice my 3.0 port to get two 2.0 ports. Will Apple ever release a keyboard that has USB 3.0 ports on it? Or does anyone know if this is in the making? I'm sure Apple would think of producing new ones if this is possible, right? I'm not entirely sure if it's possible, or when this latest model keyboard came out, however. Has anyone heard if it's in the making? Advice to just buy the current one/ wait for a new one is welcome. Thanks!
