IMO, 2012 Retina and its updates were masterpieces of hardware design. I wish they continue producing them with more up to date hardware.

Mine is still going strong. Second Apple product I ever bought (first was an iPod many, many years back), and since I've been a bit of a convert! The battery only lasts about 2-3 hours now, so I replaced it with a new model last year. It did have issues with one of the keys but it seems to have come right. I much prefer the 4 USB-C ports over the array of various different ports on the 2012 rMBP, especially because I can plug the charger into either side, but I do miss magsafe a little.

Loved my 2012 Retina. It served me all through a Comp Sci degree, and has now gone to friend who is still studying.

Still using mine ($1999 model) and having a hard time justifying a replacement - especially with all the consternation about the keyboard.

I'm thinking about upgrading when they announce a 6 core, but I'd like to see the keyboard addressed - and a 4k retina screen would be a nice touch.
