What a nightmare! There are many cool features like the
versatile equation solver and list manipulation. However, the
integration of all these features into menus is a terrible mess. It is
never clear what will happen next when
a function key is pressed - nothing is intuitive. The lack of RPN does
the
rest and leaves you puzzled if for example the % key is pressed... |
