Closing in on 7 years since Apple made a 17 inch laptop some people just can’t move on.
I love my 15" 2012 rMBP and it's honestly the best laptop I've ever used. I've moved on, but if someone is going to ask me, of course I will say I'd rather have a 17" for my work laptop (have much different preferences for personal laptop that I use at home and take with me on vacations, though). I don't expect the 17" to come back (though maybe they can get to 16" by reducing bezels).
I'm fine with the 15" display in current models, but have other concerns about the current generation, but that's another topic.
