It isn't designed exclusively for bagpackers. That is only mentioned on the Verge article, while if you look on the starlink page you will find no such reference:
https://www.starlink.com/specifications?spec=5This is useful for working away from home somewhere on the mountains. Where you have a cabin, have some proper solar panels setup and doesn't make sense (finantially-wise) to keep a starlink installed permanently there. The other option is car-travelling, not everything needs to be solar and using electricity from a gasoline car works great while using little space on the storage.
It isn't meant as side partner for your walking hikes.
