Yeah...2012 was so long ago.
So...what sort of "redesign" do you think needed? i.e. what's missing that isn't already there? And...why is the current design so bad?
Exactly. There is nothing wrong with the current design. However I do think the next wave of Macbook Pro's will look more similar to that of the new Macbook. I also believe that Apple will be ditching the glowing logo on the lid like they have done with the Macbook.
I am happy with my 2015 Pro and won't be upgrading anyways, the only upgrade next year will be the iPhone, having an iPhone 6 at the moment.
