I'm a Linux guy too, when I have to use a Mac I turn all the gloss off and it's ok, but without going to Nix I miss a system wide package manager and I like an open-as-possible community OS that runs everywhere. It's a shame Apple doesn't license their chips.
About a year ago I got a maxed out Macbook Pro, but the above combined with the fact I wasn't comfortable travelling with something that cost as much as a good used car made me return it.
Now I'm using a Thinkpad that was ¼ the price and it's great, AMD chip, 64GB of RAM, replaceable storage, fantastic screen, keyboard (and Trackpoint) means it can do just about anything. Yes, battery life is limited, around four hours with the 16" OLED (I haven't put any work into optimizing it, and this isn't a battery-first model), but I can handle it. I'll maybe get a Strix Halo laptop since I like running LLMs, but otherwise x86 has improved enough that it's pretty good. That said, I won't complain if it matches/surpasses Apple chips, and I'd consider running a headless Apple 'server' at home.
Now, 7.5 years later, the battery is not so healthy any more, and I'm looking around for something similar, and finding nothing. I'm seriously considering just replacing the battery. I'll be stuck with only 8GB RAM and an ancient CPU, but it still looks like the best option.
Another useful thing is that you can buy small portable battery packs that are meant for jump-starting car engines, and they have a 12V output (probably more like 14V), which could quite possibly be piped straight into the DC input of a laptop. My laptop asks for 19V, but it could probably cope with this.
That doesn't sound super secure to me.
> for five hours.
My experience with anything that is not designed to be an office is that it will be uncomfortable in the long run. I can't see myself working for 5 hours in that kind of place.
Also it seems it is quite easily solved with an external battery pack. They may not last 12hours but they should last 4 to 6 hours without a charge in powersaving mode.
Don't you drink any coffee in the coffee shop? I hope you do. But, still, being there for /five/ hours is excessive.
I'm guessing you're well aware, but just in case you're not: Asahi Linux is working extremely well on M1/M2 devices and easily covers your "5 hours of work at a coffee shop" use case.
It's not 8-12, and the fans do kick up. The track pad is fine but not as nice as the one on the MacBook. But I prefer to run Linux so the tradeoff is worth it to me.
just... take your charger...
My Apple friends get 12+ hrs of battery life. I really wish Lenovo+Fedora or whoever would get together and make that possible.
