> I don't get why Apple are apparently going to be putting them into the new MBP line later this year.
Apple has apparently being going to put a touchscreen in a laptop every year since the iPad came out, and it's never materialized.
Because it would blur the lines between the iPad and MacBook to much. Right now it's two clearly distinct product lines, with separate use cases. Adding touch to the MacBook could hurt iPad sales (in the pro segment).
I also think Apple knows that their laptops doesn't need touch. It's a gimmick and adds nothing to the usability, but raises the cost.
Previously, those were rumors from enthusiasts who wanted to see it. Now it's an internal leak so there's a lot more credibility to those rumors.
