Well, this is probably the only point where I disagree with Douglas Bates. I found using grouped data introduces a level of indirection that makes life more difficult. And, if you check the examples in this list, very few of them use grouped data. So I would wish that in the coming book there were more examples without grouped data, as I know that finding the right syntax for these is difficult when the book mainly hast groupedData examples.
