The Vilna Shas is a modern innovation, relatively speaking, just like the printing press, in the course of Jewish history.
And it was one developed by Christians, the Romm family.
It has no inherent kedusha or worth. It came about through chance, an accident of history. The Bar Ilan cd gives us an efficient, effective means of learning, and it should be utilized fully.
And as far as levush goes: the Borsalino hat that is so beloved in the yeshiva world only became popular after mafia movies came out. It is due only to another accident of history that this hat became popularly worn. There is nothing inherently holy about clothing styles copied from gentiles and 18th century Polish nobility. Halakhically, a talmid hakham must cover his head and wear clothing that is clean, well-maintained, and tasteful, as well as modest. This is the only requirement halakha places on such dress. You’re speaking in sociological terms, not religious ones.
