If I may nerd out for a moment, the technical manual [+] for the Enterprise (NCC-1701-D) even specified that the entire craft could be piloted from a PADD. This is entirely reasonable based on today's mobile device hardware (I'd argue, if you're offloading computationally expensive tasks to a central processor and using a mobile device solely for taking in aggregated sensor data and outputting navigational commands).
Well, let's be honest, mod the implementation details, Star Trek pretty much got this correct with the PADD.
