The next hurdle will be the TSA's 100Wh limit on batteries. It's illegal to fly with anything larger. That's why Apple's largest 16" Macbook Pro has an exactly 100 watt-hour battery. If some laptop can charge at 150W or 200W, then presumably it would draw enough power during normal use that'll it need more than 100Wh of battery to be usable for a long time.
