From NS 7.2, SM is your ticket. NS7.2 was just Mozilla Suite, nothing Netscape about it. Mozilla Suite morfed into SeaMonkey. Except for the gingerbread user interface, she will find no difference in using the SM suite.
I have learned that SM suite, both users and developers are mostly in Europe. So, you know, it's like driving a BMW or an Audi.
I have never used the full suite in any of its forms. But I can tell you that the browser is solid as a rock, more robust than Firefox any day.
