it seems to me that the use of a touch screen to get stuff in to you inventory would be faster then using the mouse. would this be allowed and would it really be faster?

I don't believe it would be faster because as soon as the computer gets a signal to click, or in this case, touch the screen, it would take the same amount of time. Even if it was allowed, it would all depend on your reflexes to touch the screen as fast as you could. To test it, it would depend if you're fast enough to match or beat the WR for the category.

I have a touchscreen monitor, and it works well, but I barely use it. I would test it, but I think I already debunked the theory of this method being faster.
