Hello, after having my white plastic 2007 macbook far so long, I decided to upgrade it! I just purchased a new 15" retina macbook pro and I'm awaiting delivery. I was pleased to find out that they now have a HDMI port. I did some more searching and the product description on http://www.johnlewis.com/231656820/Product.aspx say that it's a "HDMI input". I am to assume that this is a mistake on John Lewis's website? Surely the HDMI port is for output (to a TV). Can someone confirm that the new MBP's have HDMI output.
