I ran into this issue at my school and had a few professors get frustrated by students with laptops. However we talked about it in class and came to the determination that the people who are using laptops to screw around are only hurting them selves. And besides whose paying the tuition? This would be one thing if this was High school but not college.
I have always considered experience more important than CompTIA certs. Not to take away from the ability to get these certifications but I found the 3 years of IT experience in internships I had accumulated before graduating with my BS in CIS to be a more valuable asset.
