We're in the same boat. I'm using the last 2012 pre-retina unibody 15". With maxed out RAM and SSD it's adequate for nearly everything I've thrown at it. It's also had an admirable run, so I'd be happy to buy again at some point... but a matte screen matters to me. As does a good keyboard. And being able to swap out the drive. All more than any spec or form factor improvements that have happened subsequently. So while I'd be happy to have replaced this laptop by now, maybe even more than once... Apple simply does not sell replacements for this laptop. They sell laptops which have a mix of regressions and somewhat improved performance (and they're thinner!). And past a point of meeting certain demands, the regressions matter more than performance gains or ounces lost. Maybe when it finally dies, I'll see if I can find a serviceable 2015 model. Or maybe by then WSL will be an acceptable alternative and this will be the last of half a dozen Apple machines I bought. And they'll be as happy about it as I will, because as many pundits, product managers, and fans like to say: maybe people like me just aren't part of their target market anymore.
