You can plug computers into the HDMI port of any new TV already, right? Whats the difference between a TV and a large display, for the purposes of the average consumer?
None whatsoever. I know lots of non-technical people who do exactly that, without having the faintest idea of how their laptop magically outputs stuff to their TV. To them, in that use case, it becomes much the same as the DVD player or video recorder they're used to; it just so happens that it also does more than either of those two things.
