So I am going to try and write a quick update from my phone. While I do think that touchscreen is convenient for phones given the limited real estate of increasingly small devices I don’t believe it ports well to something like the pc.
Both windows 8 and the new apple OS are planned to feature man phone touchscreen UI changes. This presumes that the phone UI is something brilliant or intuitive when most of the UI layouts I’ve used are designed by necessity. They are trying to make the best out of a very limited input system. I suspect once the novelty has worn off both companies will return to the infinitely more convenient and versatile systems that they’ve been using for at least a decade.
Or more likely they’ll try to force the change onto people till they just accept it. Judging by the gaming industry.
