From what I've encountered in class, the only use for a laptop during lecture is for the partiers to look at Facebook for the next party and for some of the girls use AIM to IM other classmates about how the teacher has a fake Coach bag. So a processor above 400mhz and a wifi card is appearently all you need. Personally, I just sat there and spaced out, kinda daydreaming about random nothingness. I'm easier to amuse than most.
