How fast people forget the real keys on mobile phones and the outrage when touchscreens were coming out...
If you think about it though, how is your typing accuracy on your phone vs keyboard? Much weaker I presume.
The reason it works so well on the phone is, it isn't just an on screen keyboard, but effectively your mouse/pointer tool, to click, to navigate/swipe/scroll. It also enables you to have a bigger screen.
So it takes away from the typing experience, but gives you a lot in return - a very valuable trade. On top, you don't do heavy amounts of typing on a phone as in, writing essays or lines of code - accuracy/speed isn't that important as it is in a professional environment.
On a laptop however, the keyboards main and only real purpose is keyboard inputs. What are you gaining for a 2D/touch keyboard that will justify the loss off productivity?
