Battery life?
My company-provided Dell laptop has a battery life of 30 minutes. Between car chargers, power banks, solar chargers, and public outlets, battery life hasn't been an issue for a few years now. That being said, I do think the M1 MBP battery life is pretty amazing.
Fans?
I can live with them or without them. My iPP is silent, which is cool, but my world doesn't end when fan noise kicks in on my computers.
Burning?
uhhh, just take it off your legs?
Specific software?
I don't understand why I, as a consumer, would ever want that? Why lock myself into Apple products?
I don't mean to argue; I get what you're saying, and I'm sure things will be great ten years from now (privacy issues aside), but today, answering the OPs question, I don't see why the M1 would be better than the i9 16".
Now, I would never buy the 2019 16" mbp, but that is because of the integrated parts, not because I think it is outclassed or obsolete. I hate the thought of having to replace the entire computer if there is an issue with the storage or ram.
Anyways, I'm monitoring this thread because I have a hard time believing the M1 MacBook is significantly faster than the dGPU Intel MacBooks, even the 2013 MBP. I'm hoping someone could provide some real-world evidence. A quick search will show me seemingly infinite comparisons, but a closer read reveals the author is using a mbp with Intel HD, or Intel Iris graphics; it is quite tiring.
