On my last E190 KLC flight, they were taking most, if not all, rollaboards to be gatechecked.

This did not go down very well with an American passenger that boarded after me; once he stepped aboard his fury boiled over, and he announced to the entire cabin that the bins were big enough for his case, and kept the commentary up for the duration of his walk to his seat with some choice words for the staff members he passed.
