Battery life is the only thing stopping me from getting out of the Apple ecosystem. As soon as a viable Linux laptop with "enough" battery life becomes available, I'll make the switch. At that point there's nothing on Apple side that couldn't be done better in Linux (with a bit of work, but that's okay).

I travel a lot, and often on standby for work during that time. I need to be confident that when I pull the laptop out, there's ALWAYS enough juice to respond to a situation immediately without worrying about anything else.

If Framework offered hot swappable batteries, even if a quick restart is required, I'd be fine with that because at least I wouldn't be stranded in that case. And I'd be happy to pay as much as a MacBook, or a bit more even, purely for ideological reasons. Apple's dominance is bad for all of us.

Instead of a hot-swappable battery, why not just carry a large battery-bank that can charge your laptop over USB-C? That way you don't even need to reboot.

Browsing around on Amazon, I see there's actually quite a few battery banks that with over 60W of output, and ~100Wh of capacity for under 100€

Windows ARM laptops are quite good in that regard, but I'm not sure how close they're to Macs.

I think you could shut down a framework, swap the battery, and boot back up in probably 3 minutes or maybe only 1.
