Well, that's why the redesign right? If there will be a touch screen, they will make it so that you can adjust the screen level and angle. On top of that, having a touch screen doesn't mean you need to throw away other ways of input such as mouse and keyboard. You just use it when it's necessary. btw, that is how traditional painters did in the past, sticking their arm out to the canvas. Would there be any reason why people nowadays can't do that?
Ugh, the smudges!
