I think that's just because they map a lot of files, it's
not real memory usage.

Instead of "top", use e.g. this tool:

And look at the PSS information.

(PSS information changes depending on how many apps are running
as unlike RSS & VmSize, it takes memory sharing into account.)

Most of the apps are fine in 1GB even if you run a lot of them.

Only things like www-browsers, LibreOffice and manipulating large images 
e.g. in Gimp are really memory hungry.

(Real-time video editing is already otherwise too demanding for
these machines. :-))
