You are stuck in the past.
I go to class twice a week and some attendees have tablets.
He is a full-time university student. I suspect twice a week would be an approximation of how many days he
doesn't[/u] attend.
All the class textbooks are available for downloadable PDF format.
That doesn't seem particularly relevant. Also you are basically suggesting they read PDF files on a
smartphone. Only a person who has not tried to use a Smartphone for reading any modicum of actual content would think that is a usable alternative. The screens are far too small for anything but casual use.
But standard size Laptops are not allowed. Notebooks are a safety hazard and they are distracting to others.
On what basis do you come to the conclusion that Notebooks (presumably you refer to laptops, not actual Notebooks) are a "safety hazard"? How are they a safety hazard? And how are they any more distracting than a tablet?
It is a high density auditorium with no desks, only theater seats. Tablets t work well in that environment and take less space that a pile of textbooks.
Key phrase, "Tablets work well in that environment". Of course nothing to really substantiate the implication that they work better than Laptops, but at best it's anecdotal.
Building auditoriums for 50 people is not cost-effective.
Lecture halls usually accommodate several hundred or more, with plenty of personal space or even desks. And this ignores the fact that despite your assertion otherwise, desk space is not required for a laptop any more than for a tablet or smartphone.
Get rid of the desks and and have a big room that holds 140 people and not violate safety codes.
Lecture Halls don't typically have desks.
