I still have a 17-inch, Early 2011 MacBook Pro. I upgraded the RAM to 16GB, put the 500GB HDD in the optical bay and added a 1 TB Samsung 950 Pro SSD. In many ways the 2016 rMBP 15-inch is either a non-upgrade for me or even a downgrade. I like 1920x1200 resolution. I wanted Apple to do an edge-to-edge display and eek out a 16-inch display in the 15" body and make it native 3840x2400 resolution. I also wanted them to include Intel Optane 3D XPoint SSD storage. 32GB, 64GB RAM options would be an upgrade. The I/O is much faster in the version they released but more than 1TB is really expensive. The high price and the USB-C ports aren't the top of my list complaints. I don't understand why Apple isn't placing more blame on Intel and how they're holding back enhancements to the MBP. Their new processors are later than they promised and they haven't met low power requirements for larger RAM quantities. Intel Optane 3D XPoint is dragging -- I've recently learned this could be legal entanglements with the intellectual property.
