That's because it's made now and isn't meant to be a setup for a film from 1979.

It's a different story set in the same universe it isn't a route map to Alien.

As for Nostromo being a Model T.

It travels faster than light, it keeps the crew in cryonic suspension and it lands and takes off in one unit.

The two ships practically do the same thing to the same level of sophistication only one is a space truck and looks dingy and older and the other is a science vessel/corporate ambassadorial/store window ship and looks flashy and new.

It's surface details and surface details change extremely fast (I noticed this morning looking in the mirror).

I'm with this logic all the way. Perfect sense to me.

I wanna point out that from what I know about the film, people who are interested in this only as a set up to Alien are in it for the wrong reasons and will be disappointed. To make a Star Wars analogy in regards to this as a Alien prequel, this won't be "Ah, so that's how Anikin became Darth Vader" it's more like "Ah, so that's how that dragon skeleton got there". Which is possibly a much more interesting story.

...did that make sense?

I could be wrong. There's a lot of conflicting info out there.
