As someone who has used both a DAW and musical notation software in the past, it must be mentioned that they are two completely different paradigms. This product is designed for writing musical notation. A DAW is designed for manipulating the arrangement of samples in a multitrack timeline.
That's a very narrow description of a DAW. OP was specifically talking about the piano roll - a feature that obviously differs from traditional notation but is still very much related since both aim to achieve the same goal.
A DAW surely isn't limited to sample-based arrangements. In that light your description of a DAW isn't wrong, but very much unrelated to the point OP was trying to make.
