Well, this IS a magazine meant for the Swedish speaking community and from my personal experience, all these terms are in pretty wide use in the Amiga community here. I'm not sure if you mean that you speak Swedish or not, but it would take up way to much valuable space to include an explanation for every computer term there is for there are quite a lot of them.
"Skärmar" does mean "screens" and "dataskärmar" means "computer screens" ("data" means computer or computing). Swedish doesn't like to reuse the same word over and over so there are a lot of different words used for the same thing.
With "flat hard disk replacement" I did mean flat stuff like CF cards. Paper is flatter of course, but for me at least a CF card feels flat and a 2.5" HDD does not. I used the terms because several of the articles where about flat screens and small HDD replacement cards so the term seemed fitting.
