Just looked it up, I see the appeal of just toting this in your hand while flying with no other baggage (assuming the battery lasts forever), but what’s the price again? The center review said it’ll cost almost 10 grand.
Yes it's pricey, though you can get one almost new from eBay at 1/3 of the retail cost.
And yeah the batteries are great, `powertop` reported 55h battery life remaining at 60% backlight with a single `st` terminal window open. And the backlight is blindingly bright at the max setting, so it's also usable in direct sunlight.
The laptop will also charge off of any USB-C power source like the weakest phone charger, makes me think that it'll take charge even from serially wired potatoes.
