I was in college in the mid-2000s and the lecture halls had all been refurbished with ethernet ports at regular intervals along the tables. We'd bring our laptops and cables to class and plug them in. It was like "wow, this is modernity."
If they'd have known how soon wireless would arrive, they could've saved a lot of money. In fact, if memory serves me, I was using ethernet as a freshman and wireless as a senior.
