16GB, 1TB.
To be fair, I don't really need all of the power of the 16", but the last 13" couldn't take on Fusion 360 properly especially at higher res. I'm hoping M1 will allow me to do that with the much more powerful GPU. Apple did demo Fusion 360 running just fine in Rosetta 2, so... that was my "you got me" moment.
I won't wait for an M1X/M2 chip because...
1. We still don't know if it's February, March, April or even WWDC.
2. If M1 works, then M1X is just overkill. Then there's the matter of whether M1X being more powerful will drop battery life.
3. Given M1's pricing, I can already guess what M1X's pricing will be.
4. Apple will still most likely go with the old design for those then.
TSMC just got on 5nm and the M1 is as a result of that. They won't move on to 3nm until around 2022... and that coincides nicely with the last transition playbook: 2 years after the "first ones", a redesign comes, with much more powerful chips.
2 USB4/Thunderbolt ports are enough for me. My "docking" solution at home is now a single Thunderbolt 3 cable for everything. So I in fact don't really use more than 1 port at any time.
