This is really great! My 28S is falling apart and held together with tape. With this calculator I think I will finally retire it.
You need to go to the website for a great tutorial and documentation.
Considering what I paid for my reliable old 28S, this is a steal.
Ill miss the "cigarette case" look and feel though . . . .
Woo! Woo! about ND1, v1.2.8
