In many ways a good network is the thing that makes a laptop program worthwhile in the first place. Is there any study of the difference between desktop rich technology schools and laptops schools. In that case do the laptop students engage in more group work, write more, use the computer more, etc. Portability is often cited as the big motivation. Schools could save on the purchase and then each student would always have exactly the chair best fitted for them.
Most places find it easier to have seats in places where people sit.
Laptop programs are wonderful for getting a school to work together to invest a lot of time and money and attention on technology. Lots of committees and people basically stake their reputations on it. Maybe that is a good thing. I tend to think about the Music Man. I don't want to misquote here, but from what I read Joel's point is well taken.
