The long and short of it: These days we have just about all of the computing devices seen on the original Star Trek. We even have some devices never dreamed of by Roddenberry and the folks at Desilu. Our memory is fuzzy on this, but we don’t remember ever seeing a PC sitting on or under a table or desk aboard the Enterprise, nor do we remember seeing anything resembling a laptop — although something that looked suspiciously like a Nexus Tablet did make a cameo in 1968’s “2001: A Space Odyssey.”
