Has anyone actually received one yet, though? I can't seem to find any actual reviews.

If you configure a StarFighter model on their website, it says it will ship in "4-5 months" and have a production run of 1000 units. So not out yet.

They also offer a more moderately priced StarBook model which ships in "4-5 weeks". Fossbytes gave this laptop a generally positive, though not outstanding review: https://fossbytes.com/starbook-mk-v-from-star-labs-review/
