I've never understood why this wasn't included. I mean the iPad has it -- why wouldn't the MacBooks? It would be another remarkable difference from PC laptops. It was remarked above here that you have a hotspot on your iPhone but the great thing about it being included in the MacBook would be that it knows it's on LTE and thus be careful with data usage.What do you guys think about adding a cellular connection to rMBP/rMB
But there are lots of other things that don't make it to the MacBooks. TouchID for instance.
