Frequently, the subject of the demise of the computer mouse appears in the news, citing the touch screen as it's successor. To me, this appears as a catastrophe. I see so many problems that I hope it does not happen. Can someone explain how it can handle the graphic details? How about the wearying of arms that would have to reach all areas of the screen with incredible finger tip accuracy? Would not sitting so close to the screen generate visual problems? I expect many more objections can be made. These are just a few for starters.
