I agree completely with Mr. McAllister's points. None of the five findings listed in the original posting are unique to laptops. PCs or networked PCs accomplish the same thing. Laptop students participate in more project-based instruction.
Laptops lead to more student writing and to writing of higher quality.
Laptop students make more presentations than Non-Laptop students. I have not read the thing cover to cover however, so I speak in partial ignorance about the study. Nonetheless, my remarks are about these claims and similar ones. I think that my initial reaction is to think about The Music Man. A laptop program better be great.
