The most interesting thing so far that I have seen from #CES is this Lenovo foldable. Of course it's not the first ever foldable but they seem to be doing the behind the scenes tech right. I can see the book mode being extremely useful for translation and the second screen on top in vertical mode looks amazing as a means of seeing the results of whatever you are doing on the other.
I'm not a big fan of the 3-screen horizontal setup lots of artists use but I can see myself using this.
