Abstracts really should include research design. I'd need to know if groups were randomly assigned to long hand vs. laptop before the research is even worth considering. And I'd like to know if a "no notes" group was part of the study.

Even though I personlly agree with one concept in the abstract: if I am typing then I am doing ear to finger transcription. Long hand for me means doodling and never again looking at the notes. But I figure I occupy the noise in most studies.
