Was listening to this podcast about OSX Lion and it mentioned that the new trackpad gestures are much more memorable than keyboard shortcuts, especially for "average" users.
Which seems to resonate with this question on keyboard shortcuts - saying that most people dont use them.
So, do you think that is where the future is - touch gestures and not keyboard shortcuts?
Personally I cant see it changing things much - while there is a keyboard, but then I dont learn many either - but probably more than "average".
