If people are banned from taking notes on laptops, then they should be banned from taking notes on pen and paper also.
The laptop has much more of a chance of being distracting. Pen and paper can and does, such as old school IM (passing notes), but its about killing the slippery slope.
I personally support all bans on all (personal)technology in a classroom setting. This includes phones, laptops etc.
What happend to the Socratic method of teaching/learning? =(
I just see overwhelmingly more times than not students using aim/facebook/meebo/yahoo games/ during class. I'm sure there IS an argument to be made for people that actually use their laptops to "optimize" learning, but they are few and far between imo.
