With the advent of Windows 8, several PC manufacturers have introduced notebook computers that also operate as tablets - the screens separate or fold over so you can touch, swipe and gesture on your laptop the same way you would a full blown tablet. That's led to a predictable question: When will we see a touch-enabled Mac? My hope is that day will never come. There are better ways to interact with your Mac than to touch the screen. Leave your touching to the iPad.
