I'll try them at least ...
I'm a .NET + web developer and security aficionado. I work with Linux VMs and docker a lot.
Currently I'm using a M1 MacBook Air with 16GB RAM and 256GB disk.
- The 16GB memory of my Air is already fine. My memory rarely gets under pressure (and even if, I don't notice it). Imho upgrading to 32GB isn't worth the price ... I don't get any real-world benefit out of it.
- The base 512GB disk will be perfectly fine for me. My Air is using 220/256GB. I will appreciate the additional space, but I won't need 1TB.
- However, when working with docker and VMs, I'm constrained by CPU cores. Therefore I'll go with the new 10 core design. If I could, I would upgrade to 12 cores ... maybe with M2

- Since I don't game on my mac and I'm not into video production (lol) I don't care for GPU cores on a MacBook. 8 or 14 cores ... doesn't matter for me. So I go with the base option.
- When working in the office, I work on my MacBook Air connected to a single 32" 4K display. So, it's nice that the Pro can do 2 or 3 screens, but I guess I won't use that .
The biggest upgrade will be the screen:
- 14" always was the sweet spot for me (between portability and screen space). I'm glad Apple finally did what Lenovo did years ago.
- I'm used to 144hz on my large screen ... so I'm glad to finally have 120hz on my MacBook.
- Since I'm working outside sometimes, I'm eager to try out the brighter screens in sunlight.
But to be honest, I don't like the new design. The case looks really fat and bulky.
Personally I could easily give up the SD and HDMI port (I connect to a projector 3 times a year, I have no problem using a dongle for that).
However I don't understand why they didn't add an Ethernet port
I got the feeling that the "Pro" in these machines actually means "Video/Audio Pro", not "Developer Pro".
I will try the 14" model but to be honest, there is a good chance I will return it and wait for the new MacBook Air M2.
