"We've done tons of user testing on (touchscreens) and it turns out it doesn't work. Touch surfaces don't want to be vertical.

It doesn't work ergonomically". - Steve Jobs in 2010 Times may change, but ergonomics do not. I do not understand the impetus for the touchscreen MacBook Pro. I feel like Apple has run out of ideas.
