Sadly I've got maxed out MBP 15" instead. Not that I don't like it at all but retrospectively I did it out of custom (I've had several MBPs 15" for several years in a row), Macbook 12" would've suited me better.
Heh. Let me tell you my Mac laptop saga...
I bought an iBook back in 2001. I loved the form factor, but the G3 was just too slow for what I wanted it to do. So in November 2002 when Apple announced the 15" PowerBook Titanium I bought that, even though what I really wanted a G4 12" PowerBook, which didn't exist. Well, dammit... 2 months later in January 2003 they released the G4 12" PowerBook.
Eventually I just bought the G4 12" iBook. When the Intel Macs came out they discontinued the 12" models. I said they needed to release a 12" MacBook Pro (or MacBook). Everyone said I was crazy but in fact Apple did release one, as the 11.6" MacBook Air. Unfortunately, I didn't like the various compromises it had, and its premium pricing, so I got a 13" MBP. And then Apple started releasing Retina MacBook Pros so I said Apple needs to release a Retina 12" MacBook too and I'd buy that.
Fast forward to 2015, and Apple released the Retina 12" MacBook, the holy grail of laptops I had been waiting for... except the keyboard sucked and it was pretty slow. So I waited. Finally in 2017 they vastly improved the keyboard and also significantly improved the performance, and I bought my trusty 2017 Retina 12" MacBook.
As mentioned, I only got 256 GB, but I got it with 16 GB RAM. I think it would be good to offer a 1 TB 16 GB RAM model, although really Apple should be selling 2 TB 32 GB RAM 13" MacBook Pros at the same time.
