Romans would have been so astonished by any kind of computing device ("ancient", 1960s' adding-mackhines; 1970s' pocket-calculators; Charles-Babbages' (C19th) manful attempt (sympathy for him: he knew the technology of his time was not up to where his ideas were: "Oh to live for one day, 500-years from now!!") that they might have said: "deus ex machina!".
Well-known = god from a machine; a (Greek) theatrical device, adopted by the Romans; an intractable circumstance suddenly resolved by a "miraculous" event; beyond coincidence, therefore, somehow contrived.
Yes, they would have been shocked & stupefied; but, as the novelty faded, a laptop would have been seen as just another machine; brilliant, advanced, centuries ahead of its time, perhaps; but, just another machine.
Imagine friends of Julius Caeser, or Cicero, "I'll just go on my "deus", contact Latin Stack, to ask for an interpretation of what Cicero has just said to me?"
Given Joonas's dissatisfaction it is incumbent, upon me, to improve the answer!
Other colleagues have deployed computeresque-terms so cannot copy these. What about "machina visus et somni" = "machine of vision & sound"; or, even "machina visus". This may sound more like a TV; but, then, laptops are used to watch TV-progs.
As Tom Cotton indicates, these things tend to be truncated into one-word terms, "visus" = the vision. We Brits speak of wathching "tele"; never, "the television" (In Finnish?). Of course, the Latin, "visus", has a supernatural angle "The Vision!"
This concept could take us into the realms of superstition; religious-zealotry; a possible execution for dabbling in "witchcraft", if you can handle that?
Suspect that this joke is not appreciated (humour does not travel); but, if you could take your laptop back in time, what do you really think would happen?
