Why should professors worry so much about this kinda stuff? In the past do you remember college professors getting pissed over doodling or daydreaming? In high school, its different, everyone has to be there, and its almost the teachers job to mold every student into something. But in college, its different, their should be mutual respect from the student and the teacher.

Maybe the professors are pissed that some students can still do this (surf, IM) and still pass the class, which is up to them to deicide how to form their classes. But hands down, the college already has your money, what the hell should they care what you do? Our advisor said it best "We HAVE your money now...thats the easy part...you STAYING here is the hard part"
