Buying the StarFighter definitely wouldn't be the smart decision. It's very expensive, it's basically a pre-order of a product that's already had its shipping date delayed, it's the first gen/batch of that laptop series so hardware bugs may be present, and my current laptop has 11th gen Intel so it's not that old.
Why would you want a 16" laptop? The furthest you can take it from your desk is your couch. Anything further and it becomes cumbersome and awkward to carry.
