As a freelance designer I really appreciate my 2011 17" (16GB RAM, 1TB SSD). For some of us who literally need a 'portable desktop' to work on at client sites for 8-9 hours a day, any extra weight is a small price to pay for a half-decent screen size. At nearly 50, I can't really see the pixels on my non-retina screen but like the extra physical size. Especially as I use a Wacom tablet in front of it which means the screen is a bit further away. If I can carry my 2011 MBP around (I do, and yes I admit it is heavy), I would love to have a 17" modern one, which would be smaller and lighter than my existing one, and I wouldn't be constantly worrying about logic board failure. Although I guess I'd have to worry about how to pay for it and whether the keyboard would last! I'm aware that my age and use case makes me a tiny subset of Apple's target market, and it will never happen, but one can but dream.
