I think this works effectively in many situations (particularly keynotes), but I frequently give presentations that are (1) meant to inform more than persuade or entertain, (2) are often given to an audience with a substantial fraction of non native English speakers, and (3) the slides are regularly distributed after the fact. This pretty much necessitates having texty slides that I have to read more or less verbatim, even if that makes the experience more dull.
