Asus replaced the touchpad on its new ZenBook Pro with a 5.5-inch touchscreen
I think this is a wonderful idea, given that touchscreen responsiveness and power optimization have been a focus of research over the last decade. At worst it's a touch pad, at best it's so much more. Of course a lot depends on how software developers will embrace it - and I hope Linux users get some love. (I wish Asus and reviewers will stay away from gimmicks like watching movies on it.)In any case, far better than removing a set of useful keys from the top of a physical keyboard.Add: this also enables new types of casual games, similar to Wordament, Angry Birds etc. Oh, and better smudge tools on Photoshop.
