To the commenters: if you read the article it doubts the validity of the picture:

"The above photo may be the work of a PS junkie or it may just be the real thing."


please, you should be more accurate when you give news..... that pic it's absolutely a fake.... nice try

look at the size of that pad and single button... no way is that practicle. i find the pad on my pro is bad enough for catching when typing, with that thing you will have no choice but to rest your wrists on the pad... i cant see apple making such a huge design floor to be honest.
