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.
