You know, one thing I was real curious about before seeing the movie is what the computers would look like.  The original Star Wars existed before GUI was even an expression, the few monitors they had on set were very basic, nowadays movie computers are complex and flashy, I wondered what they would do.  And I thought they actually did a good job making them feel like they belonged.  There's a write-up I found on HUDs and GUIs showing them off.

Some of the ones I liked:








(am i the only one seeing smiley faces in those buttons?)

I also like how they kept the nixie tube looking arabic numbers that were used in the original A New Hope.

I noticed because there's almost no writing in Star Wars outside of the Imperial Typeface.  But I also remember seeing a pre-Special edition version of ANH on tape or something where the displays were in English, and they redid them in alien, same with the numbers.  So I like that they brought numbers back (though I can see what look like Roman Numerals in that red bar, III, IV, V, VI etc... I guess that works too).

There's a book, which I haven't read, called "Luke Skywalker Can't Read" which made me realize "oh yeah, there's hundreds of species out there, each with their own language, of course they would have to figure out a pictographic representation that works across species.  So I made it a point to look for markings and so on in the movie.
