Okay, so they're showing that these things can be useful for more than just playing illegally downloaded mp3's, so when do the grad students get them? Doctoral students are around for much longer than undergrads, so we are in the best position to take advantage of the academic benefits of the technology. In addition, we are working on cutting edge research, which ultimately works to benefit the university as a whole. I don't think it's a stretch to suggest that graduate students contribute more to the academic community than first year undergrads.
