I'm actually typing this reply on a 2012 MacBook Pro which is still working pretty well. I've also used several recent MacBook models at work so am familiar with those. Things that I like better about the 2012 MacBook Pro compared to newer models is that it's easier to replace/upgrade items. On my 2012 MacBook Pro I've replaced the original hard drive with a SSD, upgraded the memory, and replaced the failed battery (which shouldn't be unexpected for such an old laptop) which were all fairly simple to do.

I also do not like that Apple has completely removed all USB type A ports on the newer MacBooks. USB type A plugs are still very common and I wish Apple left one or two on the newer MacBooks in addition to the USB-C ports. Yes, you can use USB-C to USB type A adapters but it is annoying.

I also do not like that Apple has removed the Ethernet and microphone jacks. Both jacks are still useful to have on modern computers. I'll make an exception for removing the Ethernet jack on the MacBook Air to accommodate a thinner chassis but wish the MacBook Pro chassis was kept thick enough to accommodate the Ethernet jack.

2012 Retina model had all the relevant ports, a great keyboard & screen, an Intel CPU and Nvidia GPU - the go-to choices for professional software development to date, making it much easier to design locally & deploy remotely.

Build quality was also stunning. It’s still good, but the gap between brands is shrinking.

Arguably the worst part about modern MacBooks is software. I don’t know anyone who finds it more stable/convenient to use or pleasant to develop for :(
