In the new TV series Alien Earth, the low resolution CRT monitors and clunky keyboards aboard interstellar spacecraft really stand out. Presumably it's an homage to the 80s' movies.

Mostly im sure, but using older and simpler technology does have benefits when it is going to be used on ships traveling for decades at a time through space. Seemingly the mass of ships in the Alien universe doesn't seem to matter too much so chunky old tech that is easier to repair and hopefully more robust could make ships both cheaper and more likely to return from the apparently not uncommon ship disasters.
