Unfortunately, it seems to me that "ticking the box" is often the approach PTC takes in the development of Prime. Graphs, especially 3D graphs, are a tick-the-box solution. They are extremely weak. Text formatting is a tick-the-box solution. We still don't have subscripts and superscripts, and it's a math program! Result formatting is a tick-the-box solution. Version 3, and we still can't set the exponential threshold! There is lot said about the fact that Prime is missing a lot of features, but always in the context of major features, such as scripted components, etc. The problem goes much deeper than that though, because many of the the major features that have been implemented have been implemented so poorly that they are in no way equivalent to MC15. The major features are often missing minor features, sometimes to the extent that they are all but unusable (3D graphs and exporting graphics are two examples).
