Is it really easier to write? Every note has to have a line that extends its full rhythmic value past the notehead -- you can't just write 10 circles to say "this big chord fills the whole measure". Every accidental must be marked on the note -- so if you're writing a piece in C# major and it doesn't diverge from that key, you're going to have to notate the accidental on every single note. EDIT: they do allow key signatures; they just don't mention it in the example or intro video. And every notehead's shape varies based on the pitch class (i.e., C, D, E, etc.) -- so except for "E"s (empty) every note head has some decoration you'll have to do... you can't just make a spatter of dots/stems with a slash over them for eighth notes. For some music, this seems like it would be a bit more work (mainly the varying noteheads); for other music it'd be a serious problem.
